Hello mate, can you check in ur browser if Adoble Flash is enabled?
Follow steps:
1 - Type the following where you would normally type a URL:
chrome://plugins
2 - Locate the Flash Player in the list of plug-ins. You may see more than one Flash Player listed.
3 - Select Enable for each Flash Player listed.
In other case:
You can use a Virtual Free VPS like rabb.it only for verification purposes.
I've made account and Coinbase allow me to send Documents (Flash Works). Rabb.it is totally free.
http://rabb.itProof:
(Remember if you're going to use Rabb.it you need to Upload your Documents and Download into Rabb.it in 'Download' folder, another Folder you will get Failed error.)
