Um...in the plugins folder you should have 3 folders. Betsiel, Turbine and TurbinePlugins. The Beta_LuaPlugins is the name of the 7z file that the Turbine and TUrbinePlugins files are in before they are are unzipped. Did you upzip them before you put them in the Plugins folder? If you did, then I'm not sure what could be the issue.
And a soon time frame is just stupid. lol They need to give you guys a date! I don't know why it's taking so long. I sorta feel bad.
Hopefully it will be released to EU before Christmas. lol
