The fact that you said you installed VE PRO 5 months ago is even more reason why you need to upgrade. VSL has almost completely moved all of their code to a single platform, meaning all of their products are so tied together now you almost need to update all of them when they release a new update to something. Especially when they update VE PRO 5. So here is what I would do:
1. Do a system restore point. Don't ever think about upgrading your software without some type of backup to get you back to where you were.
- Go to START --> RIGHT BLICK "COMPUTER" --> choose "PROPERTIES" from the menu
- Click "SYSTEM PROTECTION" on the left
- Go to the "SYSTEM RESTORE" tab at the top of the new window that pops up
- Click on "CREATE" button, and give it a name of "before updating all my VSL Software" and let it finish. Close all the windows when done.
3. Login to the VSL Website and go to USER AREA --> SOFTWARE --> and then download all of these from the left (be sure to pick the Windows version): Save them all to one folder.
- Vienna Instruments
- Vienna Instruments PRO
- Vienna Ensemble PRO 5
- Vienna Imperial
- Vienna MIR
IF YOU OWN IT - Download Vienna Suite also but I don't see it in your signature.
4. Install them now in this order:
- VE PRO 5 (reboot)
- Vienna MIR PRO (no reboot)
- Vienna Instruments (no reboot)
- Vienna Instruments PRO (no reboot)
- Vienna Imperial (no reboot)
- Vienna Suite if you own it
5. Now reboot your machine. Do not open Sonar or the VE PRO 5 server. Instead, first open VE PRO 5 STAND ALONE.
6. Try to add an instance of:
- VI PLAYER FREE
- VI PRO 2
- Open an instance of a MIR PRO STAGE
- Add a Vienna Suite plugin to one of the added channels
7. If all those things worked then you are ready to do all of this with the server version, inside of Sonar. If you need any specific setup instructions for Sonar, they are in the manual.
About your automatically open a VI PRO 2 channel, I am not sure what you mean because I do not know how you're doing it. You either have to click the button on the bottom bar of VE PRO 5, or you can hit CTRL + SHIFT + N and it will add a VI PRO 2 instance.
Hope that helps,
