Troubles with saving a modified path

I am using R2011a. I am trying to copy my collection of scripts from an older XP computer to a new Windows7 computer. I have tried a couple of things but most recently I have been copying my scripts to a SanDisk, moving the SanDisk to the Windows 7 computer and copying the scripts into the Windows 7 computer. Then I fire up Matlab and under Set Path I add the folder and sub folders. I can run scripts OK but when I want to save the path I get the following:

"Matlab can not save changes to the path" "The path file, pathdef.m, might be read only or might be in a folder for which you do not have write access."

The message goes on but in essence I can not save the path for some reason.

Can you point out what I am doing incorrectly?

Thanks.
