I have just uninstalled my old DimPro and installed the DimPro 64 bit supplied with Sonar Producer x2.
 
When I installed it, it asked for a serial number. I entered the one on my registration page I got when I bought X2.
 
Now when I start it, it says "Error opening midi device", and over that opens a large dialog asking for a registration number.
 
I enter the registration number as it appears on my registration page, next to the serial number.
 
It tells me my registration number is incorrect.
 
I copy-paste the number.
 
It STILL tells me my registration number is incorrect.
 
I double-check serial number (which I also originally copy-pasted) and registration number. They are correct.
 
I reboot my PC and try again. First, "Error opening midi device", then the dialog.
 
Still does not work, neither typing (taking care not to muddle 0 and O), nor copy-paste.
 
Anyone else experience this?

Postscript: I have just tried all my old registration numbers as well (I originally purchased DimPro 1.0 on DVD) - none work. (Not that I expected them to. The newest serial number is clearly displayed)

Are running DimPro as adminstrator?

that was it. But it's still not showing up in Sonar X2.

All the others are there: Zeta+, Zeta+ 2, Rapture, etc.

Just not DimPro.

I'll do another posting. This is getting me down.

There is a long trhead about this in the SONAR forum.
