LC Games will not play . . .?

Greetings;

I am hoping someone can help me with my issue?  First, I downloaded some of the LC Games and they worked flawlessly.  I, then reformatted my PC and then tried to Play some of the games.  I am very disappointed, now, because none of the games load anymore and as a result, I cannot play any of them.  Can someone help me and tell me what I can do to fix this issue?

Thanks,

Rick
