[23:19:15:462] System.ApplicationException: Cannot run Tick before running Start first!
   at TreeSharp.Composite.Tick(Object context)

[23:19:15:462] Cleared POI - Reason Exception in Root.Tick()

Can someone please asisst me in fixing this I am making my own Bot to just stand around the AH looking for good deals after it looks in AH but I cannot get it to even start as this is thrown

The only time I've seen an error like that... was my first attempt at writing my own behavior tree-walker using the TreeSharp primitives.

Before you can call Tick(), Start() must be called exactly once for the (sub)tree. Once you obtain a final result (Success, or Failure--not Running) from the (sub)Tree, you need to call Stop() exactly once. These are entry criteria enforced by the TreeSharp nodes themselves.

My final tree-walker looked like the following:

        // Visit the next node in the tree--we may not get a final result.
        public void     VisitNextNode(object context)
        {
            // If the node is not running...
            // It means we either: 1) have never run the node before., or 2) obtained
            // a 'final' result from the previous iteration.
            // Either way, we need to start or restart the tree, respectively..
            if (!IsResultRunning(_rootNode.LastStatus))
                { _rootNode.Start(context); }

            // Tick the node...
            // If it returns a final result, we need to stop the tree (we're done).
            if (!IsResultRunning(_rootNode.Tick(context)))
                { _rootNode.Stop(context); }
        }

        // Walk the tree until we achieve a final result
        public void     WalkUntilFinal(object context)
        {
            while (!IsResultFinal(_rootNode.LastStatus))
                { VisitNextNode(context); }
        }

        // Returns 'true' when result is final (i.e., RunStatus.Success, or RunStatus.Failure).
        private bool    IsResultFinal(RunStatus?    runStatus)
        {
            return ((runStatus == RunStatus.Success)
                    || (runStatus == RunStatus.Failure));
        }

        // Returns 'true', if the result indicates the node is still running.
        private bool    IsResultRunning(RunStatus?   runStatus)
        {
            return (runStatus == RunStatus.Running);
        }

If this isn't your problem, you'll need to provide more context as to what your doing, and what your code looks like.

Sorry you've just confused me more XD here's my code from file:

#region Declarations

        public static LocalPlayer Me { get { return StyxWoW.Me; } }

        #endregion

        #region Inherited Abstracted Methods

        public override string Name
        {
            get { return "AuctionBuddy"; }
        }

        public override PulseFlags PulseFlags
        {
            get { return PulseFlags.All; }
        }

        public override TreeSharp.Composite Root
        {
            get 
            { 
                return new PrioritySelector(
                    CreateQueueBehavior()
                ); 
            }
        }

        #endregion

        #region Overriden Methods

        public override void Initialize()
        {
            Log("Starting Auction Buddy!");
            Styx.Logic.Profiles.ProfileManager.LoadEmpty();
            Log("Blank profile loaded!");
            base.Initialize();
        }

        public override void Start()
        {
        }

        public override void Stop()
        {
        }

        #endregion

Will someone please help, I can't seem to work out why it's doing it

Never mind fixed, the issues was that I wasn't caching the Root Composite, you need to do that.

e.g.

return _root ?? (_root = Composite());
