Problem with loading from mac

Hi everyone

I am encountering a problem when I try to load the Warcraft (3.3.5a) client from Mac. For the past year I have had no problems when I run the Wow.exe file from my documents and open it using WineBottler to convert to Mac. I recently tried to load up warcraft but when i click the wow.exe file and open it via WineBottler, nothing happens. I have tried deleting and re-downloading winebottler but this has not resolved the situation. Does anyone know what might be causing this problem and how I can successfully open the Wow.exe client?

(UPDATE). I can open a separate 2.4.3 Client so winebottler is not the problem I dont think. Any help appreciated thanks

Many thanks
