Default [Q] "Unmount in Progress"

That is the message I get when I try to mount an SD card in my Gtab. When I power up, I get about a half dozen force closes, including Clockwork and Titanium. It lets me unmount the card, but when I try to mount it it sticks on the "unmount in progress. None of the apps that I installed or that came w/ the rom show up when I look at the SD card on my pc or at the internal one through a file manager. Almost everything FCs or crashes. Someone please help !!!

Thanks

BTW- I am using the latest version of Vegan and have been since it's release w/ no problems
