Hmm, here are some other cax files...

Thanks for your responses joecar.

Actually, I've been 'playing' with the V7.5 tuning tool after recently purchasing the software.
Initially, before the tuning tool would function it was necessary to download the latest updates,
which I did. So yes, the V7.5 software is installed.
Initially and prior to purchase, I downloaded the V7.5 software, then I downloaded the V8.
Maybe I should delete the V8?

I know its not rocket science and shouldn't have a problem.
I don't know, maybe I'm one of those guys that could screw up a wet dream if given the opportunity. :(

V7.5 and V8.2 co-exist.

Try re-installing V7.5.

Try re-installing V7.5.

Did that and saw several changes in the 7.5 folder including the addition of the 'calibrations' folder.
Thanks!
