Cant change sound patches in CB4

Hi

I'm using Banstand in Cubase 4 as a VST. Had been working fine but suddenly will no longer change sounds. I can change the first sound and then it does nothing when I drag and drop a new bank. I am ICT Tech for a school and we have 7 workstations running this and it is happening on them all - unfortuanatly, this is a major part of our music teaching resource and is causing our music teacher (and therefore me too) major headaches. I dont want to reinstall as I believe with the new reg tool you only get 2 re-installs - is that correct?

Ideas anyone?

 

Have checked version numbers of the plugin and standalone and they are the same. Also, the library appears to be complete.

Oddly, the patch changes work fine as long as I dont use a preset - ie a blank soundbank!

This isnt ideal unfortunatly as we use a custom preset with a custom Cubase defualt song file for our students

 

Nope. You can only be activated on two machines at once- that's the two authorizations part. You can reinstall as many times as you want.
