I don't know what warmane is - this isn't the WoW forums so you need to provide details here.
Is wow 3.3.5 x64, or x86? Is Warmane a seperate .exe file you run?
That crash is indeed typical of the crashing that LAA fixes, when that happens you need to check
1. How much RAM was the game using (Or measure how high it is when not crashing, so we can see if it's 2GB of 4GB limited)
2. How large your page file is - try setting it manually to 16GB
3. How much free space is on the page file drive (100GB)
Virtual memory is Physical memory and page file together - but when it comes to older game engines VRAM is included in there as well, since that's duplicated into system RAM.
The LAA mod will only work for x86 titles in an x64 OS, to raise the 2GB limit to 4GB. It can't let it use x64 amounts of RAM (above 4GB)
A quick google shows the game uses the 2GB limit normally, so high resolution gameplay (and high texture quality) combined with any mods, is going to cause it to run out fastest.
The Warmane forums had answers for this - including linking to here.
