After opening the software Websitex5 professonial 17 - entering in my project - and clicking on a Textfield that i want to adjust, the software freezes. It dosen't open the textfile and the Software dosen't react at all. 

I can only shut off the whole software websitex5 via Windows Taskmanager.

I've tried PC restart, cleaning PC cache, it didn't help. I use Windows 10. Project is normally saved on pc.

What shoul i do?
