That's exactly what I will do I remember doing that when I first put this rig together.

I will report back with anything I find and let you know when I head back from Cake.

I am putting a SSD in the computer in the next couple of weeks so I don't know weather to try and fix this now or wait as I will have to go through everything once I put the drive in.

If you're using the SSD as a system disc and loading up from scratch, I'd wait mate.

No point in beating yourself into a pulp over something that might be cured under a fresh OS.

Even if you only installed the 64 bit version of X1 there are a number of "built in" vst/i that are still 32 bit. Thus the error could still be bitbridge. Open the windows task manager once the project is loaded in sonar and look for bit bridge.exe in the list. If it is then you have a 32 bit vst/i running if not then you should be 100% 64bit. @konradh the server setting you referred to are the bitbridge server settings under preferences>file>vst settings.

@ Bristol. Thanks I will give it a scan over and see if anything stands out but you are right I would be best holding fire if I am going to do the reinstall to the new ssd.

@ Tom. Thanks I will look for the bit bridge but I have seen this issue happen on 2 blank sessions from start up that are 64bit. Its also not jut one specific project its happening in.

Its all a bit strange
