InfoPath 2010 and REST web services, custom code button firing twice and second click fires error

Question

Hi,
I have two supposing simple issues which I'm having problems correcting.
If a add a button to the form and write some custom code (See below) to submit some data via a REST Web Service data connection. The code runs but somehow fires the URL twice to the web service.
I've also recreated similar functionality using Rules on a button and some concat formulas and exactly the same thing happens when I the run the data using the Query Data Action, it fires the URL twice at the web service.
How can I stop this.
Secondly, if I use the custom code route, it work correctly the first time it pressed except for the double fire issue, but the second time I click the button the InfoPath internal system throws up an issue. See screen shot below.
Any help would be appreciated.

fqcFileLocation = fqcFileLocation + "?TestName='HugeArse'";
fqcConnection.FileLocation = fqcFileLocation;
fqcConnection.Execute();

Hi Phillip6653,
Did you check the similar
thread to uninstall the windows update KB2756920 which was published on day 1/10? After auto install the update, on day 1/11, the same error occur when I open site using designer, after I uninstall it, it works for me, please have a check.
