So I been having this problem wor a while now. The previewer doesn't work. So I need to build an .exe every time I want to test my projects. It worked before and same problem even if I try a new file. I already tryied uninstalling the program and didn't work.
What operating system are you running?
r1.2 works great on Vista
Develop games in your browser. Powerful, performant & highly capable.
But It worked before, so I don't think it's about that...
Also it does the same with the debugger... Does anyone know about this?
Problem solved. It was a virus on my computer wich effected some of the exe files.
