What version of AE (exact version number from the Help>About box - down to the last decimal)?
What operating system? What are your system specs?
What's the full text of the error message?
Have you ever been able to save with AE before?
How are you trying to save? Did you open a file from a network drive to which you don't have write permissions?
thanks for your reply!
after effects CS5 - version 10.0.0.458
mac - OSX v 10.9.4
processor 2.93 GHz Intel Core i7
memory 4GB 1333 MHz DDR3
message given: After Effects Warning: could not create the file '/Users/alyson/Current Work/BiRD/AEtemp-21301C-BIRD new_3.aep'.
Yes usually saves no problem - have tried to save also as a copy and in a different name but still get same message...
This is a file of mine which I last worked on in July
First: You are trying to run an application on an operating system for which it was not developed or tested---and on which it is not supported. See the system requirements for After Effects CS5.
Second: You are two big bug-fix updates behind. Rather than running version 10.0.0, you should be running version 10.0.2. Details: http://adobe.ly/DVA_updates
Ok thanks - I'll update the bug-fixes now
