I've just joined up using the App but I've been here for years and i paid the extra couple dollars for tab pro but on the site it's asking me if i want to try the demo. Is this an entire different thing i have to pay extra for or what?

Thanks in advance...
Has anyone else been having issues with TAB PRO as of late? The songs wont load properly lately and I cant play them or switch between the different guitars, not sure if its my computer or the tabs
