Warcraft III and CDROM drive error

[Billabong2020]

Hi all!

I have a back-up (you might even say pirated) copy of Warcraft III English version. I installed everything correctly, without any errors. I tried to run the game in any way I can (splash panel, startup, cd-rom), but a window keeps popping up telling me to make sure the CD is inside the cd-rom drive, and click retry.

The CD was inside the drive all the time.

What's up with the game? Is there a patch of some kind I could use for this?

I really need help here
