Error Hardware MAO file

[CR87]

Hi all,
I've tried to do an add on on a closed OPS file.
Unfortunately, I received this error message "Bad MAO hardware file format on or near the line: 102".
I've tried to fix it, but I still got this message.
Which could be the problem and what could I do?
Thank you.

Not use hardware files (hardware.mao, ***.hw) from PBX (OPS saved from PBX), use initial hardware files from OPS (or extract from zip).

Great! Now it works! Thank you.
