My manage mods button on the launcher does not seem to be working it looks like it is but the window never opens up help?
Which build? Is the little window, with the message "Scanning for rF2 mod files....", opening? If yes, be patient, give it some minutes. If not, did you try to run the modmanager directly?
When you have Build 798 installed, you can find the Modmanager in the folder: [Your rF2 installation-folder]\Bin32\ModMgr.exe How long did you wait when the "Scanning..." window opened? Don't close it when nothing more happened after 3 or 5 minutes. Like i said before, give it some (more) time.
Since 2 days ago I got the same problem but window closes fastly, I see it just 1 tenth and then goes... I tried using direct access on Bin32 folder but happened the same. Some solution?
