[Jprogramming] Error - "bad jmf header: assert" using addon jdb

[Stefan Scott Alexx]

Hello -

I am encountering the following error when attempting to use the addon "jdb"
(using J602 on WinXP32):

   load 'data/jdb'
   demosandp_jdb_ jpath '~temp'
|bad jmf header: assert
|   'bad jmf header'    assert 0[free fh,mh,fad


Does anyone know how to correct this? Thanks!

I installed the addon "jdb" using the Package Manager following the
instructions here:

http://www.jsoftware.com/jwiki/JAL/Package%20Manager


The above error message occurs when doing the first example (sandp),
described here:

http://www.jsoftware.com/jwiki/JDB/Examples


Entering the first line above appears to work:

   load 'data/jdb'


However, when I enter the second line above:

   demosandp_jdb_ jpath '~temp'

this returns the following error message:

|bad jmf header: assert
|   'bad jmf header'    assert 0[free fh,mh,fad


Thanks for any help!
