How to resolve MODULE_DOES_NOT_EXIST error for new portlet script?

Hi all,

First post here, and sorry it's a request for help. I'm trying to create a new Portlet script in my company's sandbox environment. In the past hour or so, previously ok files are failing with the message below when I add them as a script. I can upload to the Document Cabinet fine, but creating a new script yields the error.

This is happening to all my Portlet scripts, even those I know worked previously.

Is Netsuite having general problems at the moment, or is this a specific issue with my instance?

Thanks you

Steve
