Fatal error: Class 'VmModel' not found

[BASiK]

Bought this Virtuemart module. [So VMSlider] http://www.smartaddons.com/joomla/extensions/item/141-so-vm-slider
I am running Joomla 2.5.1. It worked PERFECT in Virtuemart 2.0.0, but 2.0.1f is screwing it up

it gives me an error of.
Fatal error: Class 'VmModel' not found in /home/sturdi/public_html/joomla2/components/com_virtuemart/helpers/cart.php on line 148

Note: I am required to upgrade to 2.0.1f because of the issues 2.0.0 is having with the price and shipping sections being all screwed up.
If someone is willing to genuinely work on this with me, I would be willing to share the module with them to check out the code.
[ If this is not allowed, disregard it =) ]

I think it is not needed to share the module, I added it to the config, so it should be loaded
