on the complete offer page are 3 tabs trialpay, fyber and supersonic. trialpay is the one not working and has been this way for several weeks. supersonic is the one with yahoo community video which works just fine.
there is an open forum in the bug log about trialpay since when you click on anything and get url is invalid. WGT CS says its their page and they are the one that needs to fix it. you need to read the post in between mine from jay which gives you url paths and their direct email which WGT would not give out. ( receipts@trialpay.com ) blow the email up, send them several each day. you will get an automated response email so if they dont respond keep sending. check the forum on trialpay out.
