Android rom flash help :-/

[GTI]

I think I'm fooked
First the good news, I managed to get both Odin and CWM on my Samsung Galaxy Tab 8.9, so I can basically boot into both of them. And with Odin, it connects to my PC.
The bad news is that I seem to have erased the stock rom, in that the tab only goes until the boot screen and then freezes. The question is, how can I get a custom ROM onto the tablet if its not mounting correctly on my PC? The Tab 8.9 doesn't have an SD card slot, so I can only copy files across to it when its recognised by my PC. I was thinking Odin was the way to go, but all the ROMS on XDA are zip files, and Odin needs MD5.TAR

Any help much appreciated
