Now using X2 and putting together my first new project since upgrading a few weeks ago. The issue is, I can load EZDrummer into the project and set up the tracks like I have done in the past with no problems, I can preview grooves, but when I drag the groove to the track I get a message that says "Cannot find or open file"       I've never had this happen....Any ideas? Should I do a uninstall / Reinstall?    Thanks, Ken

Sounds like Sonar or EZ Drummer aren't pointing towards your groove file folders wherever they are located. Some kind of scan is probably in order or adding of system folders but I don't know how to do that with grooves in Sonar or EZdrummer. Maybe check the manuals.

Ez and X2 here and all is well.  That's a new message to me, too.
 
Did you just install X2 on top of X1 and everything else (i.e. existing plugs etc.)?

Yup

and the other funny thing is it wont dock for me....I need to minimize it.

I noticed I only have the 32 bit version installed. that could be part of my problem.

Are you using x64 EZdrummer?
 
I seem to remember reading something about 32bit plugs not docking in X1 x64.
 
I'm clutching at straws..  Is X2 seeing the 32 bit EZdrummer?  Does it have the bit bridge icon?
 
Where are you dragging the MIDI     files from - EZD or the browser?
 
I'm off to bed now (it's twenty to three here), but I'll look in in the morning.
 
Hope you get this sorted..

I think this is where the problem lies. I downloaded the 64 bit updated back in July but when I run it, it goes through its motions but the EZDrummer64 does not list in my programs. And when I run plugin manager I only see EZDrummer 32 bit. I think I need to reinstall tomorrow. 

Our posts must have crossed.  It was the multidock issue that rang a bell.
 
Hope that sorts it.  Post back if re-install does or doesn't work..

I can't get it to recognize the 64 bit version. Getting irritated.
