Well I'm about to give up anyways.

Heh.
I've tried flashing it on my brother's PC to no avail (he has windows XP). Right now I have restored my FW to the original using iXtreme 1.2 but am unable to flash to iXtreme 1.4 using flashix.bat on the new FW. I've tried so many things and I just don't know what else to do.
Is it really bad to continue using iXtreme 1.2 if I can't get the upgrade to 1.4 done?
Have you grabbed the package since 3 hours or so ago? I posted in this thread that i updated the package to include revised batch files for better handling. Re-grab and test.
