Slow Database & Rates Randomly Calculating at Zero

I was directed to this link when I was told that the system we purchased was having (and constantly has) issues that causes crashes or delays. This most recent issues makes me believe the system is flawed because it is randomly zeroing out some attorney fees. I am not sure how to fix this since all the rates are in the system and it isn't zeroing out all of the rates or attorneys. Does anyone know of a patch to fix this?  Any help is greatly appreciated.
