Eleven Rack #2 issues

Hi everybody,
After I unfortunately unplugged the Eleven Rack and switched USB ports I've been getting the dreaded "Eleven Rack #2" problem.

It's happened to me before and I followed the Benoni video with success.

However, this time round something's amiss.

The "midi input device" is greyed out within Pro Tools.
There is no hidden Eleven Rack in Control Panel.
I cleared the cache from the Editor.

Within the Editor everything's fine.
That said, Pro Tools constantly sees the phantom Eleven Rack and will attempt to communicate with it during a session. Yeah, now THAT'S a fun session, right?

I've uninstalled drivers, used CCleaner and everything else out there that i can find.
Does someone have any more insight into this insane problem?

Thanks!
