I'm not sure if it's the version of Crossover, or whether it's the latest version of Uplay (dated 24 April 2015), but the program no longer runs for me in Yosemite 10.10.3.
It fails with an error: "Uplay has detected an unrecoverable error and must be shutdown. Crash dump created at "C:/Program Files/Ubisoft/Ubisoft Game Launcher/crashes". I can provide the dump, but it's gibberish to me.
The error first occurred when I tried to run Uplay after updating Crossover and it did an automatic update at opening. I deleted the entire bottle and re-downloaded the installer, but the same error occurs.
Is anyone else running into this?
EDIT: I should have noted - I've updated Yosemite, Crossover and Uplay since I last tried to run it, so I'm trying to figure out which is the problem before I submit a ticket.
