[Wine] problem with opening programs which used to work...

[maya.tzunz]

Hi all, 
I hope someone will be able to help since I didn't find useful answers at the FAQ section...

I had a few games which were working just fine using Wine, until they stoped doing so... whenever I try to open any of them it says
"The program X has encountered a serious problem and needs to close... This can be caused by a problem in the program or a deficiency in Wine..."

So little details...

Does anybody have an idea?
Many thanks in advance...
