Hi Retro Games Revival and...hello to Brazil ;-)
On the second image I can see a link saying "exibir conteudo do relatorio de erros"...does it mean "show the error report"?
If yes, could you click on it and send me the content?
From the second picture I can read "system.io.fileformatexception" that indicates an error on a file format.
Anyway, I have some questions...would you please answer them?
Did you re-install mGalaxy + if you're using a "supporter theme", do you have the latest version too?
Did you install in the "Program Files" folder? If yes, could you try to install in "My Documents" for instance?
Which emulator are you using for the test ?
Can you see the interface of mGalaxy before it crashes ?
Do you have the opportunity to run a test on another PC with the same system (you are on Windows XP, aren't you?)
I remind you that if you're running mGalaxy on WindowsXP, you'll need:
