I'm not sure if it's related, but maybe you need to manually remove the .bom files for the driver in the receips folder, as i explained here:

I would deinstall everything, then manually remove everthing with com.line6. in that folder (there should be nothing left if it worked properly) and try to (re)install everything, if you don't have a working driver right now, ..
