About firewall setting,what should i check exactly?
You are running an out of date version of After Effects release 2015, so you should seriously consider updating it. That won't help your current problem, but 13.5.0.x was the buggiest version of AE I can remember. If you're running the CC 2015 release of AE, you should be on 13.7.1.
To solve your problem, you should install the newest version of AE which is the CC 2015.3 release. The latest version of that is 13.8.1.
still the same on the latest version of after effects
Update Premiere Pro too.
THANKS MAN! U R GENIUS ,IT WORKED! I UPDATED AE & PR TO LATEST VERSION THEN, THATS IT! THANKS AGAIN YOU SAVED MY ***!
THANKS MAN! U R GENIUS
