Could not rename warning received from AfterEffects

Hi Experts,
AfterEffects CS5 fails to launch with a warning. I get a ‘Could not rename file’ warning with a file name path. The complete warning message I get from After Effects is shown in the below screenshot. But the strangest part is that such a file does not exist in my system. I attempted checking for this directory on the terminal too. And I failed to locate it. I have run permissions and restarted my system but still this message refuses to go away. What might be the reason for displaying this unrelated warning? Does anyone have any idea? Please share. Thanks in advance.

After Effects warning: Could not rename
the file ‘/Users/Jonahlee/Library/
preferences/Adobe/After Effects/12.0/
Workspaces.
2091.1407351739436081.xml’ to
‘Workspaces.xml’.
