Illustrator line thickness fault

Hello TB people, my first post, exciting :slight_smile:

I know this issue has been brought up many times but I have an issue I could not find solution here or anywhere else.

I have an issue when importing illustrator files int TB and thats that the line thickness does not maintain itself, it gets thicker for some reason.

I export in CS2 format. Everythong works well besides them pesky line thickness.

Any ideas? Preferences u’d recommend?

Much appreciate,
