WoW Always Crashes After 1-2 Hours

Have any thoughts on why WoW and WRobot lock up randomly (WoW crashes and I have to restart WoW + WRobot to get it running again)?

[F] 20:50:23 - [Spell] Cast Slice and Dice (Slice and Dice)
[E] 20:50:41 - Error injection: Cannot launch it, skipped.
[...]
[5+ minutes of the above error repeating]
[...]
[E] 20:59:25 - !Memory.IsProcessOpen

This happens to me every 1-2 hours spent in-game running a profile without fail. I have yet to run a profile for more than ~2.5 hours since buying WRobot.
