Error bms script please help me [namco_games_ar.bms]

[retroartebox]

Hi, I'm new to the forum and I do not know if I can create this post in this way, but I need help. I'm trying to extract the file from a ps2 game. It's called '' ARQUIVOR.AR ''.http://aluigi.org/bms/namco_games_ar.bms

but when trying to extract I get this error that is in this image



I do not know what I'm doing wrong, I'm selecting the file '' .ar '' directly, if someone can help me I'd be grateful, sorry for being so dumb e.e.

You can try this script too:

Anyway note that it would be necessary to have the archive (or its "filecutted" version) for analysis
