Encoding fails with RGB Curves after update.

Question

I'm trying to finish a project, but Premiere is gving me troubles..
I'm uisng Creative Cloud and I saw that there was a update for Premiere and i thought: "Why not, it can't hurt..", but boy was I wrong!
Before the update I could play and export my sequence without any problems (except laggy Playback), but after the update Premier wouldn't play the sequences (only audio) and when I tried to render previews I got an generic error.
After some investigation I found that there could be a problem with RGB Curves, and sure enough, after disabling the RGB Curve-effects on the Clips it worked fine!
I also found that it should work fine with GPU acceleration enabled, so I activated it. Now my project played fine in PP (with RGB Curves), and thanks to the GPU it didn't laily
Happily I started the export and went for a walk, but when I got back the exports had stopped and there was an generic error!
So, apparentely the exporter(/media encoder) doesn't use the GPU (*sadface*) and so is affected by this weird bug.
What should I do now??
I use RGB Curve for color correction and grading through the whole sequence, so I guess I need to find another effect that gives me the same result..

I generally try to be careful with updates, and I should have known better (especially than update in the middle of a project). But given it was a minor update and that minor updates is supposed to fix bugs (and not introduce new features/bugs..) I thought it would be safe.. But it's a weird bug (that couldn't have been fixed by replacing the RGB Curve effect file with an older version!?) and even weirder is that the text I read was for CS5.5..
Luckily I had also installed PP on my laptop, so I just copied the program files from the laptop to my workstation and I could carry on and finnish the project.
The thing about waiting with updates of this kind is that you don't get the bug fixes. It's one thing to wait before you jump on the next big update (like CS5.5 to CS6 etc) and another to install "bug fix updates".
There is no real "infancy period" for minor updates, they do not mature, there is one update, if that update introduces a bug, then that's fixed by the next update etc etc.
In the end, you don't gain that much by waiting to do minor updates (albeit you should avoid it during a project), since minor updates should fix the bugs that your software currently has and you could, theoritically, just end up with more problems when you do decide to do that update.
One solution could be to never update, but then you're stuck with the original bugs..
The best thing to do is to do a backup before updating (and I should've done that..).
What would've happened if I decided to install Premiere Pro a week later?? Then I probably would've gotten the latest version with the update and so the bug!?
