I have been trying (and failing) to install the mod pack on a Windows 7 64-bit system. The downloaded files work on a different computer but they fail with the following error on this one: ToEE Front-End X encountered a serious error: IO Exception with building a package: ZIP file must have at least one entry The program is unable to continue and will now close. Please report this error as a bug at the Circle of Eight community forum. Make sure you attach the full log file (TFE-X.log). So I am.
