X7 crashes all the time randomly.. cannot work this way!

I updated to the new X7 thinking it would be better than the previous version... it is not.

We have 4 computers here that use the same program and they all crash at random times.
I have been looking for threads with the same issue online and everything I read and tried has not helped so far.
I deleted temporary files, restarted the PC, ran a can, ran all possible updates, etc.

HELP!

It's not consistent as to when it crashes and if the files are large or small.
Most files are just text only and it still crashes.

Does anyone know how to fix it?

Any help is much appreciated.
