Zdoom error: Can not find MAP00? WTF?

[godlike]

Last night my computer got really messed up and I had to restore it, meaning that everything got deleted and it went back to like it was brandnew with all of its factory-shipped files and stuff. I just started reinstalling stuff, and I started to get to work on a wad. Well, I add some custom sprites, some new ones I never used before also, and when I try and test a map out with zdoom it says "Error: can not find MAP00"

I tried to make a new map wih no custom sprites or anything, and it still said the same thing, strange... it is in doom in hexen format btw

WTF? MAP00? What do I do?
I even tried making a MAP00 with no prevail...

Please help

Could not find map MAP00

I think you're meant to name the level name as map01 (that's assuming you're using Doombuilder and the Doom 2 IWAD. For Ultimate Doom, you simply name the level name as E1M1).

Can't really help you without knowing what's in the wad you're trying to load. Do you have a MAPINFO lump, for example?

How did you start ZDoom? This sounds suspiciously like a '-warp 0' somehow got on the command line.
