Assuming you have the newest version of GSAK and the newest macro version. GSAK version 6 does is not made to work on Win7. You may even want to upgrade to the newest updated version of GSAK, I have seen a few problems fixed by doing that. This is not on the front page, it is in the forums, you need to go to this thread and scroll to the last post for the install file.

I had problems helping with macro on a Win7 computer at the event. The directory where the macro defaulted to was read only and I could not figure out what to do about it so I had to have the macro save the file in an allowable folder. If you navigate to the folder with Windows Explorer you should be able to see if that is the issue. It looks like others have had issues with this as well, check out http://itexpertvoice.com/home/fixing...-folder-blues/

Also, I think the macro file you link the button to should be in
Users\*YourName*\AppData\Roaming\gsak\macros

If I had Win7 I might be able to be more sure
