MR1 Upgrade disables memory card on xv6800??

[sk2ktiburon]

I just did the MR1 upgrade to my xv6800 and now its doesnt recognize the memory card. Its an 8 gb and I already have the fix for the hcsd large memory cards. Ive tried many soft resets and reinstalling the SDHC.777 cab....nothing works. Has this happened to anyone else??? I did a backup before upgrading so Im about to go back to 6.0...can anyone help??

I also cant seem to find a working valhalla cab dor the gps fix (one was an xml doc w/5 other unreadable files, and the other just wont load up)

Many thanks
