Layout changed after upgrading from VM2 to 2.0.1

[corymp]

I purchased a VM2 theme all in one with joomla 1.7 and VM2 (stable). Everything looked great. After updating to joomla 2.5.1, everything is still great. but after updating VM to 2.0.1 h, k, n it doesnt matter... some modules are out of place. Was there any css changes going from 2.0 stable to the revisions? My feeling is that there is one css file I need to bring back from VM 2.0.

any ideas?
