Problems running Sitecore 7.2 in Azure

Question

I have a running two Sitecore 7.2 web sites in Azure where one is Test and other is Prod. The sites are copies of each other where only difference is the Prod has a public URL. They use same the same DB and usr/pwd.

After copying everything from Test to Prod the Prod site has starting throwing errors after user tries to log on to Sitecore. Looks like Sitecore tries to create a support ticket but I am not able to figure out what the error really means. Any help is appreciated.

This is Error Message

It's not creating a support ticket, it's literately saying what you need to know. It's missing a file and it expects that file to be found at D:\home\site\wwwroot\bin\Sitecore.Support.400292.400293.dll

Check your configuration files for this dll. To me it seems like a web.config transformation gone wrong (since sitecore support DLLs usually don't include 2 issue numbers.
