Warning: Failed to get MSFTESQL indexer interface

Google would have me believe that I need to install an iFilter, as if my
fulltext index is having trouble with some kind of blob-stored document.
However this fulltext only indexes varchar fields... (across ~100 tables).

This is running on SQL 2005 Enterprise Sp2, 64 bit, 16 G mem; WinOS 2003

The full error message is:

Warning: Failed to get MSFTESQL indexer interface for full-text catalog
'textcatalog' ('17') in database 'Maximo' ('27'). Error: 0x80043613(A status
change is occurring or the project is in a force paused state, so MSFTESQL
cannot accept input at this time.).

Thanks for any suggestions!
