hello everyone, I have a problem in premiere pro

yes, but I did it in two ways, importing the project and creating another one from scratch

thanks my friends for helping me to solve the problem, it was the project that was bugged

Does it help if you chose Window > Workspace > Reset to Saved Layout (the spanish equivalent of that of course)?

Beyond that, this looks like the GPU just is not playing well with Pr on this system. Can you check to make sure your driver is up to date? You should probably visit Nvidia's website yourself to make sure you're updating to the right thing, but the latest studio driver is here, which might help...

ok thanks bro i will try to do that

Try creating a new project and importing the old one and see if that helps. If not let us know and I'll come up with some other suggestions 

Yes, I've tried all the ways you suggested and none of them worked. Do you have any other ideas?

Never easy to. figure these things out remotely unless you approach this in a systematic fashion.  Have you tried the things I suggested?  If they don't help, we can try some other things.    If you need help with the things I suggested, post back and we can go into greater detail.  

no bro nothing

Go to Help > System Compatiblity Report....
