Two days ago I installed RS 2.5 (full install not an upgrade for 2.1a) but launcher just freezes and nothing happens.. I had to exit via task manager. I tried to play one turn campaign.

so here's the basic info.. I have win7, UAC disabled, antivirus disabled, NO STEAM, original installation is from DVD RTW anthology patched to BI 1.6 in c:program files, RS 2.5 was installed in c:games on a copied original RTW (outside of program files obviously) like my other mods RS 2.1a, EB 1.2 and RTR. so, where's the problem?

any help would be appreciated
