So I downgraded cosmoteer from 0.15.4 to 0.15.2(because freaking ACD man) via website, and when I tried to launch Cosmoteer it just doesn't work.I tried again this time with the task manager up and running,and it showed up on the "background processes" thingy and dissapears 4 seconds later.
I thought it might be caused by .NET Framework not activated or something so I tried reactivating it,but it still doesn't work.
I deleted all logs,saved games and lost ships
I also deleted everything in the cosmoteer file in the program files
After deleting,I redownloaded and reinstalled cosmoteer. I didn't uninstall cosmoteer because I'm afraid my ships might be lost.Keep in mind that even with the rest of the "stuff" inside the program files folder it still doesn't help
