weldments are annoying me!!!!!!!!!!!!

hello all,

i have been reading some of the posts in this section to help with my problem but not found quite the right one.

I have downloaded the iso zip file in the SW contents section on the right. i removed the profiles from that folder and inseted them into the original folder from where the weldments come from. nothing changed thow when i went to insert a structual member. so i even went back and deleted the originl 6 that where there thinking they would disapear but there still there.

do i have to update SW whenever i do something like this or is something im doing terribly wrong?

help asap?????????

thanks in advance to any help
