I'd do as suggested by IPopov50 and use Img.
VSO has been problematic for many users.
Honestly, it has worked well for me, but Img is far superior in many respects....more reliable, more configurable
and has outstanding support from its author, LIGHTNING UK!.
Also, just an FYI,
VSO has used the patin-couffin driver for many years.
Recently, I think it was late Fall '09, VSO switched to SPTI.
The patin-couffin driver is still installed with VSO, but not needed.
As a matter of fact, it has caused problems for users and VSO support recommends uninstalling it in these instances.
To my knowledge, no other software uses it.
As others said, if you ever want it back, it'll load with Fab...just leave VSO ticked on (default setting) during the install.
I'm pretty sure it loads with VSO Inspector too, although this may have changed.
