What the Hey!

Good morning. I recently attempted to rename my existing USB external recording drive,(E), in lieu of installing my new USB external drive. I probably should have just hooked up the new drive and let nature take it's course. Anyway, here's what happened. Now the E drive is named E\(j). I haven't been able to change it back and every time I try to open a Pro Tools session I get a warning that "this action can cause loss of plugins in Pro Tools" followed by a choice of opening the session or cancelling,(No, as in do not proceed, or Cancel). I'm in the middle of a session so, call me a gambler, I chose NO and opened the session. Lucky me. No loss of plug ins yet. I'm on PT's 9.0.6, Win 7. Has anyone experienced this and if so, what can I do to correct it? :eek:
