Q u o t e:
If there is more than one WoW license, click the drop-down menu and try the others. For instance, I have a WoW1 and WoW2 license on my Battle.net account. WoW1 is for the PTR, and WoW2 is for the Beta realms. Whichever name the Beta license is listed as on your Battle.net Account Management page is the one you want to use.
If you continue to have issues, please post on the Beta Technical Support Forum.
