Romcenter

I use RomCenter and ClrMame, but I don't like ClrMame because it causes strange things with my romsets. For my favourite mame I must use ClrMame because RomCenter crashes on it.
RC 2.62 is not able to create the dat file and the new beta version breakes when loading the rompath after created the dat file.
Here's the error message:

"Violation d'acces a l'adresse 004AC217 dans le module 'romcenter.exe'. Lecture de l'adresse 0000000C."

Here's the link for that mame:

I will try and see why it hangs.
