Can't purchase 2DXY SiteSurvey tools app

I am trying to purchase the 2DXY SiteSurvey tools on the Extension Warehouse. After filling in the required information (name, address, email, etc.) I click on the purchase button and an error message says the transaction can’t be processed. It says to contact the “store administrator”. I emailed Barry M., the developer, and he said the problem is with Trimble, not his software. Can someone help me get around this problem?

Thanks.


I see a pattern emerging…
Eneroth Slicer had the same problem for some users…
