Problem With Relational Connections After Upgrade BO 4.1 to 4.2 SP6

Hello all.

I need a help, I had a BO version 4.1 that has a couple of relational connections to BW that used to work just fine.

But now we upgraded to version 4.2 SP6 and those connections aren't working anymore, anyone nows a way to make then work or I have to change it to BICS connection?

Thanks.

Regards.
