Ive been using texmod happily for a while now but ive suddenly stumbled across an odd problem thats made me unable to use it

. Yesterday the texmod.exe disapeared from the folder I had it saved in, I assumed I had just accidentally deleted it and so I redownloaded it. But whenever I extract the .zip file texmod.exe just dissapears. I can see its in the .zip file by using winrar but whenever i extract the only thing that comes out is the readme.txt file.
Any help as to whats going wrong would be appreciated please.
