EDrawing Loading Error - Driving Me NUTS

I have a file that will load in the version 2007 of Edrawingson a lap top. NO problem. Have a new vista and loaded version2008and on the top lvl assembly of an e drawing I see the assembly thenI get an error pop up 2 x then I see nothing.

OK thought it was vista so went to my desk top with xp andinstalled same way same error.
(on one install actually got an error 501 for what that is worth.

OK so then I try to read solidworks files and other Edrawings. NOproblem they open fine. On both vista and desk tip.

So then I try to recopy file (possibly corrupted) no dice. IT seemsI cant open this to top level files on a new installations yet itworks on the old. They read on the Edrawings 2007

Any ideas of what to do? DO i have a settting screwed up.
