Thanks Stardust - my idea didn't quite work but I'll use the little fellows you sent me a link to.
Gary B -
Good question and thanks for jumping in.
My plan was/is to upgrade to 5 ultimately but from 3.1c I planned to go to 4.0, then buy 4.5.
So........... I installed 4.0. Then I realised all I had to do was to install all the Flexor versions in sequence. Then all I had to do was to copy all the extras I have in 3.1c over. Then I realised that to use my existing projects (about 15 different tracks/projects on the go) all I had to do was to swap EVERY device in the project with the ones from the SFP 4 folder because the projects include pointers to the devices. (Okay I could have kept these projects in 3.1c I know and run both versions). Then I realised that the simple little dynamixer I use in all my projects isn't available in 4.0 unless you've bought 4.5 or the mix n master pack.
So, basically I thought "sod it" for now because I fancy using all this for music

and I haven't got the time at the moment to do al the other work required (mother just out of hospital, new kitchen being built etc etc).
I thought that I'd leave it for a while and just run 3.1c until I had time.
So, all I wanted to do was to have the pc boot to 3.1c not 4.0 for a while.
I agree, moving to 4.0 & 4.5 is preferable but I simply chose the wrong month to do it!
But I thank you for joining in with my little farce.
