Could Someone remind me if there is a fix for the EZ2...EZ1 old project problem???

I've been working with some older projects lately that were all done using EZDrummer 1 and every one I've pulled up so far loads up with EZDrummer 2 instead (natch) and seems to have its "track" brain scrambled as other tracks...say Lounge Lizard play the bass part, say Trilian and bring up the EZD2 GUI when clicked!!??  The only solution I've found so far is to copy the midi from the scrambled tracks...delete the offending tracks and their respective synths and then re-install them.  Very tedious and frustrating.  And worse, sometimes even that doesn't fix things.  I believe there was a fix for this problem after it was found to be ubiquitous.  If you know about it...could you hip me, please!  Thanks.
