Opening file failed

I just tried reopening unity to work on my project and everytime i try to open it it gives me this error: " Opening file Temp/UnityLockfile failed: read only file system. I really hope its not corrupt. I tried opening Angry Bots and it opens just fine. i haven't done anything to the file since the last time i opened it. can anybody help?

 

1) Tried taking ownership of the folder and ensuring you have read/write access?

2) Delete temp directory

3) Create new unity project and import everything in your "assets" folder

 

I restarted my computer( should have done that before posting) and it works fine now. scared me for a little bit cause i have a lot of work into it, but thanks for the answer!

 

I am getting this same issue, running on a mac. I cannot see the where this temp folder is to delete it, i have tried rebooting and still getting same problem..

it doesnt matter what project i try to start i get this same issue so i cant even get into unity to import assets as suggested.

 

The temp directory exists in the root folder of your project along side Assets. If it's not there when the project is closed then that's a good thing.
