MaterialStudio in WinXP 64

We had installed Accelrys Material Studio Modeling 4.0 in a box with Windows XP 64 (Processor: Intel Core2Duo, Memory: 2GB RAM, HD: 160GB) without problems.

When we run a DMol3 job (following the example files or tutorials), we always get the error: "The job has failed".

We checked the Gateway and looks fine.

Also we run other jobs using other modules and everything was ok.

Any ideas?

Best regards,

Hatuey
