Hi , i just downloaded the 4 part of mapsource version of North America 2010.30 and after unrar ing the file became .exe like instructed. But afterwards when i tried to rename it as .rar instead of .exe winrar couldnt unrar it. But then i found out that by leaving it as it is (.exe) and trying to UNRAR it in that condition winrar WAS ABLE to unrar it and then using the MSI file as instructed i was able to install it and then created the unlock code and map works fine in mapsource. When i travel to NA i m sure it will be useful. Thanks a lot!!!:000a4:
