When i enable "Multiple Frames Simultaneously" option on AE5, i get this message "After Effects warning: Unable to connect to background renderer. (26::142)". I've tried all possibilities on Memory & Multiprocessing setting but same result. i installed last updates also i've installed CS5.5 but it didn't help. Everything works fine in CS4 and it renders very fast than cs5. Any idea for this problem?
Intel i7 x990 @3.47

Check your system#s UAC settings and other such security stuff. Something is blocking the port connection.
Windows firewall was blocking AE CS5 and CS5.5. i fixed it. Now cs5 works well but CS5.5 gives same problem. Strange. I'll use CS5. Thanks alot for your help
