Weather file error

Hi guys, I've been having a lot of trouble with weather files. First of all, I live in Mexico where there's only 3 weather files available for download, so I had to create my own.

I got the information from Meteonorm, exported it as a TMY2 file, then opened it in WeatherTool and created both an .EPW and a .WEA file. I open the .WEA in Ecotect and it works perfectly, but as soon as I try to use the .EPW in DesignBuilder, 2 things happen:

1- It says that the .stat file is missing (but that's okay, I'll just have to indicate the summer week and winter week).

2 - Then it prompts the next error message:

"Error de lectura C:/Documents and Settings/AllUsers/Datos de programa/DesignBuilder/WeatherData/MONTERREY.epw"

So..there's something wrong, but I don't know what. Why does the file opens perfectly in Ecotect (the .wea) but the .epw doesn't open correctly in Design Builder?

Have you requested the epw file directly from Meteoorm? We have found these files to run well in DB/EnergyPlus.

There are several meteonorm files that were built for Mexico on the EnergyPlus Yahoo Groups site.

These should work well in DB and EnergyPlus.
