Yep...I'm getting scrambled Hex reads too...I've tried saving as V5 and above, V3, etc. and that hasn't made a difference either, nor has fiddling with the compression settings.
Unfortunately, the MED website doesn't give any contact info to report this to Gerd.
I would like to think that if he intentionally 'diasbled' the save feature that he could have at least given warning in the readme that saving over old modules could and will destroy them.
Thanks for the reply, Cass...at least I can put my mind a bit more to ease that it's probably not anything crooked in my setup.
