Photoshop Crashing on Video Render

Hi,

I've got a problem with a Photoshop CS6 version I use in my office (Windows 7).

Everytime I try to export a video from the timeline to use an image sequence on a graphic software it keeps crashing. The video render initializing starts and stops more or less at 80%.

If I cancel it, I cannot use Photoshop again as it keeps restarting at anytime only for stopping itself always at the same point.

So I have to force it to close with the task manager.

Has any of you come across the same issue?

Thanks a lot for any help!

Luca
