Photoshop CS

Hi,

I am using Photoshop CS at work. It has worked fine for a long time but just started palying up this last week. What happens is when i save (locally or to networked server) the filenames automatically change. They change to a completely randon filename thta i have never heard of and this completely disables me from opening them. I have not reinstalled photoshop but think that this maybe the only solution.

If anyone has another solution to this i would be most grateful if they would share with me.

Thanks in advance.

Phil
