Hope it helps! Bonne chance!

This was a purchased copy - it's shredder 7. I think the problem might be because I installed the program on an external disk rather than the main (C\:) disk.
I've already had problems with fonts...
edit : I re-installed it on the c:\ drive and it works fine... Thanks everybody who helped - thank you Angelo for the nice link -

No problem, mate! :D I wasn't much help but I am surely glad to hear you solved your problem... :D
PS: I should start working on an opening tree as well, I just got my arse handed to me on my favorite line... :S
hello !
Is there any software freely available to create .ctg files from .pgn databases ?
