Lightroom CC will not work atall

Hi there,

     I am having problems with LR. for a bit I got the error about scratch disks being full. I finally got around deleting a bunch of photos that I wasn't going to use and it began to work. shortly after that it stopped working completely.

When I open the program it either has a blue loading circle and says all files are synced and backed up or my preview photos are blurry and will not get better and says I have 3 photos syncing that lasts forever. When I am able to see the photos I am unable to edit anything. when hover my mouse over any type of edit, it turns gray and I'm unable to select it.

I am linked to my iPad and iPhone on the same account but not sure that's affecting it.

I have uninstalled and reinstalled LR 3 times and reset the preferences twice. Nothing seems to be working and I haven't found any topics on the forum that have helped so far.

Thanks in advance for the help
