Don't know if anyone else is having this problem, but its happened to me twice already.
The Logos 4 Mac does its update thing, downloads a new update and installs it, then places the older version automatically in the trash bin.
When I go to empty it, I get an error message that says "The operation can’t be completed because an unexpected error occurred (error code -8003)."
Its given me that error twice after updating itself. I got rid of the file the first time by doing some complicated deleting and permission changing in my Windows 7 VM, but didn't feel like figuring all that stuff out again for the second time!
Any ideas on this?
