Rendering in Adobe Premiere returns "Unknown error" when CUDA being used

Hi!

I have contacted Adobe and I am not the only person with this problem. Unfortunately Adobe seems not to care.

Here is the problem: when rendering big projects (ie. 30 minute video) with CUDA technology it returns “Unknown error”. When I switch to only CPU the video renders, but it takes much longer, 3-4 times in fact. Do you know anything about it? Can I do anything to fix it? Would changing the card to get a Titan fix it?

My set-up:
GTX 780 reference
i7-4770k
32GB RAM

Thank you for your help in advance!
