When I click the "Manage Mods" button on the rF2 launcher (or open the ModMgr file), the box saying "Scanning for rF2 mod files ..." shows but nothing happens after that. I don't know why this started happening, the mod manager has worked fine for me in the past and it doesn't seem to be a build problem as it started during build 860 but had also previously worked fine on that build. Any help would be appreciated, thanks.
