Alit help with this lisp that ran in 08 but not in 09 or 10

We have a lisp that we use to insert a prn file sved from an excel spreadsheet.

it creates a beam schedule in autocad

Its worked fine in 2008 ver. but will not work in 2009 or 2010 with all the blocks in correct file directories.

Any help would be greatly appreciated. Thanks!

BMSCH.LSP

which part does it fail on ?

It created the top beam schedule heading and then the sub marks but when it starts to input the prn file for some reason it says this,
