When my PC is still Windows xp it works fine, but when it upgraded to Window 7 I got a lot of problems. The Hardisk broke so i change it and download again this tool, I turn off my Microsoft Security Essential but after I open this tool the Reinventing The Craft is gone in the toolbar. UMSWE doesnt work too so when I untick the walkable in Village Rock tile it doesnt work. My WE version is 1.21, my computer is clean, I disable the antivirus and turn it on when im downloading something. I hoped someone help me to get it work. I see numbers in the lower left corner whenever i opened my warcraft 3, its 188.8.131.5201 iIguess thats the version of my warcraft 3 if that helps.
