17.2 Padstack Editor -- Opening scripts for 16.6 in 17.2?

Is there a simple way to open padstack scripts written for v16.6 in padstack editor v17.2? It seems like a complete scripting language overhaul. 

The root of this problem is that I exported a design from TI's WEBENCH tool. However the padstack scripts don't seem to work at all in v17.2. The first issue that occurs is "Can't find window; Form.padedit"

Here's a sample part of the script:

######################## New PadStack #########################
pse_new
fillin "R10180550000000A.pad"

FORM padedit units Mils
FORM padedit decimal_places 4

FORM padedit layers
FORM padedit grid row 1
FORM padedit geometry Rectangle
FORM padedit width 17.7165
FORM padedit height 55.1181
FORM padedit x_offset 0
FORM padedit y_offset 0
FORM padedit geometry_th Null
FORM padedit grid row 4
FORM padedit geometry Rectangle
FORM padedit width 17.7165
FORM padedit height 55.1181
FORM padedit x_offset 0
FORM padedit y_offset 0
FORM padedit grid row 6
FORM padedit geometry Rectangle
FORM padedit width 17.7165
FORM padedit height 55.1181
FORM padedit x_offset 0
FORM padedit y_offset 0
FORM padedit parameters
FORM padedit single YES
FORM padedit plating Non-Plated
pse_save_as
fillin "R10180550000000A.pad"

Here's a snippet from a script I started recording in v17.2:
