Cannot save documents after updating to Pages 5.5.2
After updating to Pages 5.5.2, I can no longer save or edit documents. It just says that (document name).pages can not be created. Same thing happens if I try to export to .docx or .pdf. Please help, I can no longer work, the update completely broke my program.
MacBook Pro, OS X Yosemite (10.10.1)
