Same for me since several days ....
WGT Members Service replied that they are working on that issue .... and they appreciate my patience and understanding.
And also problem with surveys. Sinc alsoi several days I receive proposals for sureveys from www.peanutlabs.com. Each time whan I accept, I get the same reply : "We have reached our target number of completed interviews for this survey". It happens 4-5 times everyday !!!
