Error message when using Fields

[daly2011]

Hi,

I'm using AutoCAD 2012 LT and have having problems inserting/updating/editing fields. This is the error that appears

"There are no registered modules to edit fields or demand loading is currently disabled".  When I click OK the Field pop-up appears empty!  (see attached)

The BEDIT command is also not working.  It was all working up until a few days ago!

I have downloaded the most recent Service Pack and it's still not helping.

Any ideas???

As the first error notes, reset DEMANDLOAD variable (explore it in HELP).
