Upgrade to FileMaker Go 13, its free...
11 didn't always work. 12 was a bit buggy. 13 works just fine.
You may want to upgrade to FileMaker Pro 13 to write the scripts for the Touch. Download a free demo if you don't have 13 and see if that makes a difference.
You may also want to upgrade the Touch to IOS 8.
This assumes that the Touch is compatible with these versions and you'd have to research that.
