Whenever I hover on the edge of one of the sections in Adobe After Effects CC, a window pops up saying "After Effects warning: The file 'C:\Program Files\Adobe\Adobe After Effects CC 2014\Support Files\cursors\Cur_ResizeHorizontal_Left_.png' could not be found." I tried to resolve the problem by uninstalling it and then installing it again, but it didn't work. After getting frustrated, I looked at the file location and saw that I had the file. I have no idea why this message keeps popping up, even though I have the file.
Check your file and folder permissions and user privileges.
Run the necessary updates. This is a known issue and was fixed in 14.0.1 or so.
