I'm having similar problems to those others have reported. First: Mac OS X 10.10.4, two different Mac Minis (2012, early and late I think), 8 GB RAM on one and 16 GB RAM on the other. I pointed Island Rum at the i24 beta, since I still had it, but it aborted when trying to copy the files. I copied the piggs from the old app (City of Heroes i24.app/Contents/Resources/transgaming/c_drive/coh/piggs) to the Resurgence app. When I started Island Rum again, it scanned all the piggs, then gave me the options of Icon or Paragon Chat. Icon works fine: selecting that launches Resurgence, I get the login screen, then eventually get dumped into the costume creator. If I select Paragon Chat, Resurgence launches, but never opens a window, and never attempts an outgoing Internet connection. It isn't frozen, as its menus still respond and I can quit it normally. It seems like it's waiting for something that never happens. The Info.plist file mentions a c:\coh\resurgence.exe that doesn't exist. I tried copying paragonchat.exe with that filename, to no avail. Changing any of the options in Island Rum also had no effect.
