creative cloud failed to synchronize my stuff

hi,

the CC application failed to synchronize two PSDs of mine to the cloud. with 600mb they're quite heavy so i am not looking forward to uploading them again from scratch (made a backup copy today just to be sure). my cloud space is at 5gb at the moment. so i have no problems with space.

the cc app said that it was a server problem with the firsr psd. the second one just had the comment "sync. for file "xyz" not possible". what can i do now?
