Ivan,
We'd need the number-dot-number versions of the programs to be sure you had the actually up-to-date versions of each. PrPro is at 8.1.0, and SpeedGrade is 8.1x128 ... found at the bottom of the "about" screens.
When I was having problems with Sg not working a year back, the CC app kept telling me that it was the latest version ... but it was lying to me. The Sg running on my machine at the time was not the newest one ... and I waited a month after they were released to update. So it simply blew figuring out which edition it had & what was available. So ... check your versions.
