Problem is : I did input the serial sent by PGmusic and it worked (so far)
I can read in "about" dialog :Not Activated. Serial # is: XXXXXXXXXX (my serial)

If I try to re-activate, I get : "some features are disabled. Program is not activated. reason : there are files missing from your installation. You should restore original activation ticket files (How can I do that ?) or reinstall program (I already did)...

Any help appreciated
Thanks
