Lightroom storage problem

I am having issues with my storage on Lightroom 5.5 version, it said it was full 20GB so I upgraded to 1TB and its still saying its full showing a red exclamation mark on the cloud even though it says 2% of 1TB used. All the photos I want to upload have a red exclamation next to them saying there is not enough space! 

I have tried uninstalling LR, closing and restarting the Mac and this is still a problem, I cannot edit anything! Any help appreciated, thank you.
