Hi.

We'd need a lot more information to be able to diagnose this issue. If you're performing panel GMM with a lot of cross-sections, and have fixed effects, its quite easy to run out of observations.

For more detailed help, you're probably best off emailing in your workfile to us at support@eviews.com (include your serial number with the email).
