And when I type /gse in chat cant press enter and cant open addon, only from minimap it works. And when it opens I cant click "New" nothing happens. I tried disabling all my other addons but still wont work.

the command line works for me - could you please fill in the other details about Client etc?

Sure, I am using the TBC Classic client (2.5.1.38988), latest and updated. On Windows 10 Insider preview. I will try to delete my whole WTF+Cache folder and see if it fixes it, usually it does ^^
*update: it did not, console still doesnt work :( nor the create new macro icon, in fact only the import button works and when I click import nothing happens there either. Do i need to download some libraries? it was working fine with GSE2

Nah there was a problem with BCC and Classic - Fixed in #852 - about to do a new release.

Ah okay, ty sir

Hi, new beta2 update still doesn't work. Cant click anything and the console doesn't work either. made a vid
