Exception error when loading a Query Builder file created in Toad for MySQL (4311950)

When loading a Query Builder (.tsm) file which was created in Toad for MySQL 4.1 the following error occurs and although the Query Diagram loads, the actual query doesn't and, therefore, can't be run. This is only happening with one particular file. Other MySQL .tsm files load OK.
