may be this has been discussed already?
I've got big problems with version 8.1.3 (still 8.1.4 beta does not help).
I was little bit hasty to switch to 8.1.3
Still believing, that the fault would be on my side I upgraded my CPU (Quad) and the memory (4GB) (yes everything was running smoothly with Duo and 2 GB before
But problems remained.
I remembered the old installation of 8.1.1. which I did not de-install and voila - everything runs like a porsche.
So I will not blaim the development of Live and who had the inspiring idea to switch the file format within one version of software. I would ask the company very kindly if there is any possibility to patch back projects/sets to 8.1.1. to not dump half a year of work.
