Could not acquire script lock

Hey guys,
Was trying to process a script and am sure I have all the privileges to access the file but the script editor fails and I get this error message:
Script Editor
Could not acquire script lock.
The current user does not have necessary permissions to make an update (including getting/releasing locks).
OK

There are other users that also that can edit already processed script by the way.
I can’t figure out what exactly the problem is. Any idea?
Thanks.
