Hi @Toongenie; thanks for joining our Community!
Have you deleted enough files to make up space on your account? What is your plan tab reporting at the moment?
As you probably know, you can make up space on your account by moving files that don't need to sync out of your Dropbox folder and/or leaving any shared folders or Spaces that might be putting you over quota.
On a side note, deleted files don't count against your storage quota, so permanently deleting them won’t free up space.
I hope this helps to some extent and please keep me posted on your progress.
