I had the same problem unable to purchase anything. I sent a few e-mails to the WGT Admin and Tec support. Come to find out that there was an issue with the billing system.
That following weekend during their maintenance window they were able to correct most of the issues.
That following Monday I was able to make purchases.
they will email you back and give you an update.
So, email the WGT Admin and Tech Support and inform them of the issues.
Good luck. Ryan4Eagle
