DaVinci Resolve 15

Hello! I'm a newbie on the Davinci Resolve, and I have a big problem. I started to do a video from my holiday and everything it was allright, but 3 days ago when I try to open my project I was surprised because the main timeline it was frozen. The edit mode is frozen, I can't cut nothing, I can't move nothing.The funny part is that I can do everything else, like Color the video's or Fusion, except for editing the timeline. Please help me, I don't want to lose my project. Thank's!!!!

Hard to tell with that image but the timeline looks there, just not active.

Can you delect a clip in the timeline so you can see it in the inspector?
Can you save that project with another project name and try opening that project to see its different?
What do you see with a new project?

Also, please look in the menu bar, DaVinci Resolve, About DaVinci Resolve and tell us which version you are using?
then
Go to the menu bar, file, and export a project and put the file it makes, called a .drp. on this forum so we can look.

I can't select a clip in the timeline and I can't see nothing in the inspector. Yes, I have tried to save the project before with another name, I have tried to reinstall the software again but without results. When I opening the project the timeline is the same, frozen, and not active. The version I used is Resolve 15 Public Beta.

I started to do another project, and everything is fine, the timeline is fine for the new one. But for the last one it's still the same problem, is still frozen........ and not active....I think is something wrong just with that project. I'm sure you will find a solution.
Please help me with more advices. Thank's
