Webacces wd2go pro?

After entering emailadress and password on the website I could see my MBL but couldn’t acces it. In a dropdown menu I could chose between view shares (asks for username + password, when entered it says http 404, can’t find webpage) or remove device. I removed the device thinking I could reinstall it. Unfortunately, this seems not the case because it seems that you cab use your emailadress only once. Tried it wth a second mailadress but see above. Any tips?

A firewall may be blocking the access to WD2GO, locally or from the remote location.  You can also check iof port forwarding is enabled in your router:  http://wdc.custhelp.com/app/answers/detail/a_id/8526/session/L3RpbWUvMTMyNzE1NzMwMS9zaWQvKmhrZWhJT2s%3D
