Ok, I got this profile working just fine. It took some work, but it's done.
For everyone that is new to HB, and just jumps right to using the professions aspect of HB, I suggest you start by reading Highvoltz Professionbuddy guide, which can be found
here.
The steps required to get this to work, are extremely easy. Anyone can do it, even an idiot like me.
Steps:
1) Follow the instructions of the above link I provided you.
2) Do NOT download the emptyquest.xml supplied by the OP. All you'll need is the simpleprofessions.xml
3) Download the simpleprofession.xml.
4) Place the simpleprofession.xml into your PB folder.
5) Open HB and set the drop down menu to Professionbuddy.
6) Click Load Profile and navigate your way to the simpleprofessions.xml file you downloaded and load it.
7) Back at the HB main window, click on Bot Config.
8) Click on the Open option at the top left of the Professionbuddy window that pops up.
9) Navigate your way to the simpleprofession.xml and load it.
10) On the right side of the Professionbuddy window, there should now be some options.
11) Select what it is you want PB to do, and click the big white bar at the bottom left of the PB screen that says Load.
12) Click Start. Enjoy!
Any questions about this profile, feel free to drop me a message. Being new to HB, I struggled with getting this to work. Some of the above comments are a little misleading, if you didn't read Highvoltz guide on PB.
