BAM command error

Hello Forum, First time posting here.

I am fairly new to Draftsight (AutoCad user for years).  I am reusing a lot of blocks from old drawings done in AutoCad LT 2015.  I am wanting to rearrange the order of attributes inside the advanced attribute edit window.

I am unable to open the Block Attribute Manager.  When entering BAM on the command window I get an error.
