Looking at the error message, the module you are using is trying to use a version of Core.execute that was deprecated in Mendix 8.6

You need to download a new version of the module, or ask the module’s author to update it to use the new API.

Hope this helps.

What error message are you seeing? 

Usually removing the .jar files for the module in the userlib folder, then downloading the latest version of the module from the Marketplace will fix the problem.
