Some of my excel files will not open
I have run MacKeeper for the first time and now some of my excel files will not open. I get a message saying ' file cannot be accessed' The file may be read only or trying to access a read-only location. Or the server on which the document is stored may not be working'
I can open a new excel window and there are other xl files that i can open. If i right click i can view on read only - but cannot write which is not useful.
MacBook, Mac OS X (10.6.8)
