Well I'm pleased to say I now have it working perfectly, I downloaded it from the "Plogue Sforzando" web site (Thanks Noel) and it installed with no problems at all.

All very strange because no matter how many times I installed it from the BIAB 2017 PlusPak BIAB just kept telling me it wasn't installed when it clearly was for all to see, it was even in my VSTi list! very strange.

Anyway a big thank you to all for your help and suggestions, I'm now a happy chappy......... that is of course until the next problem shows up lol.

Cheers everyone,
Keith
