I have been having this problem for awhile and just fixed it if you have ever noticed when u try to Copy & Paste something in CSS it just copies about 1/4 of it? yeah its a glitch that happened with the new CSS update (well for me anyways) i ran out of ideas until i reinstalled css and it stopped so just redownload all your files and you chould be fine 
If it doesnt work I really don't know what the problem is
