Editing Parameters

[scottccook]

I am unable to edit Multiple Song Parameters. I am trying to edit the language and the Genre. I select, lets say 5 different songs, change the parameters to english and country, press apply, and get:

An error occurred while processing your update.
Please check the selected file(s).

This may be due to one of the following causes:

*The file has been deleted from your hard drive
*The file has been renamed on your hard drive
*The external drive is not inserted
*The external drive has been assigned a new drive letter
*The External drive does not have power
*The network drive is not attached

Note: Some changes may have been successfully applied.
These changes will be reflected in the song list.

I am able to edit the parameters on the (Select Single), just not on the (Select Multiple). Nothing has been deleted or renamed. No external hard drives are being used. I have spent at least 9 hours editing parameters, and now I am at a point where I can start selecting multiples BUT I CAN'T

Please help me
