I see some people are either annoyed or uncomfortable deleting cache on a regular basis - here is what I did.
Create a file in notepad, save it as a name that makes sense - mine is hb_launch.cmd and is on my desktop.
Content of the file should be something like this (change the paths to echo your environment)
Code:
echo "SVN updates"
svn update d:\games\hb3\wq
svn update d:\games\hb3\routines\TuanHADeathKnightLegion
svn update d:\games\hb3\routines\TuanHADemonHunterLegion
echo "Deleting cache"
erase "d:\games\hb3\cache" /Q
erase "d:\games\world of warcraft\cache" /Q
echo "launching"
d:\games\hb3\honorbuddy.exe
I know it could be smoother and generic, but you get the idea.
svn update d:\games\hb3\wq <--- this is where I keep this amazingly great profile
only downside to doing it this way is that wow takes a little longer to launch (due to cache being deleted every day)
