    did you check the twist option?

    Select objects to sweep or [MOde]:
    Select sweep path or [Alignment/Base point/Scale/Twist]: twist
    Enter twist angle or allow banking for a non-planar sweep path
    [Bank/EXpression]<0.0000>:

    I don't think the twist is what's bothering you, but maybe the bank option.
    What options are you getting at the command prompt?

    Something like this:
    Select objects to sweep or [MOde]:
    Select sweep path or [Alignment/Base point/Scale/Twist]: twist
    Enter twist angle or allow banking for a non-planar sweep path
    [Bank/EXpression]<0.0000>:
    or something like that:

    Select objects to sweep or [MOde]:
    Select sweep path or [Alignment/Base point/Scale/Twist]: twist
    Enter twist angle or allow banking for a non-planar sweep path
    [Bank/EXpression]<Bank>:
    Could you eventualy upload the file, please?

    Regards,

    SB

    Default banking

    Like i said, it's the banking.
    Select sweep path or [Alignment/Base point/Scale/Twist]: twist
    Enter twist angle or allow banking for a non-planar sweep path
    [Bank/EXpression]<Bank>: <-- you must enter 0 as value here
