When I cut and paste my key into my port explorer registration window I get a toolbar at the bottom of the key window with no text in it and when I press it I get another window that pops up that just says "Please Note" and then when I close that window I still have an eval version. what up??

After you copied/pasted your Unlock Code into PE have you restarted PE? i.e. Close PE and then restart it. IIRC - this must be done for your unlock code to be fully recognized. However, the incomplete dialog boxes may be an indication that you need to uninstall/install PE.
Copy and paste the key into a notepad file - then trim it to just the key - hilite and copy it from there. It sounds like you are getting an extra carriage return or similar with your c&p
