I updated the game yesterday to 1.39 and had no problem running the game then. I was even using the map editor which means i have to restart the game many times (since the game is incapable of switching from one map to another or switching from map editor to game play without crashing.) I probably did have Impulse running in the background tho, but normally i do not keep Impulse on.
This morning when i tried to run the game with Impulse off, after a while it gives me a message that it cannot find the data file and that i should make sure i am logged in to Impulse??
I do not normally run impulse and or connect my computer to the internet unless i specifically need it. I do this so i can disable all the antivirus and firewall so my computer will run faster for gaming.
No previous version of the game has forced me to run Impulse, if that is the issue here?
