The date causes an issue in the ziparchive class and not directly in clrmame....
...guess I fix it on my own and report the problem to the author.

edit 2:
found the issue (an not captured NULL pointer) in the ZipClass Library and contacted the author.

edit 3:
...Updated the 3.62a packages with the quick fixed zipclass nullpointer...doubt the author will be as quick as me ;) So redownload the package (be sure your internet cache is cleaned ;))
