I'm trying to import my iphoto library, but the "import button" does not light up. The size of the libraries is "undetermined." When I would go into the options and hit ok, the import button lights up for just a millisecond. So I hit the enter key twice to see if it would catch import when it lit up - this is the error I got "Failed to obtain image version information from iPhoto library." I'm not sure what to do.
