Firesnails

For my problem above I just had to redownload/install it again, must have gotten corrupted somehow.

I used the mediafire download link from https://www.dkpminus.com/blog/wow-2-4-3-download/ and I believe I followed the proper steps for it to launch but when I try to connect to the stress test it acts as if its offline. The real problem is when I try to connect to the PTR#2 it tells me I'm missing TBC download files. The website stated that all I would need to do was download and run the setup and change the realmlist and I've done all that, what did I miss or mess up?
