It works! Thank you very much for the help, and yeah, i changed my settings for all the programs and keep getting errors everywere. I gave all the programs the administrator permission and everything is working normally again. I apreciate your help.
I was playing normally on servers with doom explorer for a few weeks now, but lately there is an error that says: Error launching game, errorcode = 740. I've already looked over some forums but I haven't found anything related to errorcode = 740. If anyone can help me I would appreciate it very much :)
