I think some other users in a different Thread had the same issue with the whole application doesn't start up at all. I'm using different hard drives for my games, one of them is an external. I have The Multitool on my H: and the Source SDK on my E: drive. The Source games are mainly on my H: with a few of them being on my E: drive. Is there any possibility without having to move every game to one single drive to use SourceMultiTool? Thanks in advance :)
PS: Is there a tutorial how to map properly, as most I've found are pretty outdated and say that there are way better ways to create maps nowadays.
Have a great Day.
