VM2: Reinstall to get Authorize.net plugin? HELP!

[RockOut]

I installed VM2 on my Joomla 1.7 install.

We need to use the VM2 Authorize.net plugin, which as I understand is now available in the most recent releast of VM2.0.1K

Should I uninstall VM2, then install the updated package? HELP!

Is it possible to install ONLY the Authorize.net plugin?
