I haven't touched it for some time, so I assume the forced Reforged update broke it as it did for others.
I had classic Warcraft 3 for a long time but I'm having trouble starting it now. I decided to get back into it but it wouldn't let me play on both the classic and new launcher, so I made a support ticket. I've had and played WC3 for years but stopped playing, and I don't have the CD anymore, but I always had it installed.
