EZ Drummer not recognized

I just installed Cubase 6 and when I loaded a project that was created in Cubase 4 my EZ Drummer VST instrument is not recognized. Do I have to reinstall EZ Drummer?

Not really a lot of info you´re providing, but probably you simply need to set the Vst 2.x Plugin path in C 6 as explained in the manual…

Thanks for the reminder. I forgot that I had my EZ drummer plugin installed on a separate hard drive with my samples. All is well now.
