BB Curve 8350i :: Cannot Convert Sim Card Contacts To Contact List

This has probably been covered, but i recently went to update OS to the 5.0, but while it was loading, the thing crashed and said a fatal error had occured. i had to go back to an older version, 4.6 i think, and now my contacts will not go in the contact list. I see them on my sim card, but when i try to copy all contacts to my contact list, it copies 1 contact, 8 times. its the damndest thing i have ever seen. i did not do a backup before the new install, my fault, but now i cannot get my contacts in my list. Has anyone had this problem or even heard of such. I called tech support, the only thing they said was it was probably a bad sim card, and to take it to the local repair store.
