Gosh darn it, Unity is destroyed !!!! hit a bug that makes no sense !

Well, I was working with the test version for 3 days now, today, i imported some assets like Pro Platforms2d and few others, imported some sprites, splices, no errors, saved the project, every thing is fine. close unity, reopen unity and now.....

and the result :



Everything is destoyed ! no inspector, the tabs above the hierarchy view is messed up, the spliced sprites don't show up, and the errors grow more and more

 

I had almost all the beta plugins there for few days, don't think it was related to something like platformer pro because they shouldn't destroy unity*.dll files, when i closed unity before this, everything was fine then i reopened ,,,,,

and i think the only way to handle this right now, without having any back up of the installation folder would be to uninstall and reinstall the version !

 

Maybe it's something related with the Editor layout? You may try reverting the Layout to the factory settings:
