Lynne, I think what he is trying to do from beginning is:
Take members (usernames, password, names, etc) from ctvtec.com and put them on nyvtec.com so that those members don't need to register on nyvtec.com . One challenge is that ctvtec.com already has its own data, users, etc, so "site cloning" is not a choice.

@ctvtec: The way you did is very error prone. I hope you have your backup for nyvtec.com . My suggestion is that:

1. You do some experiment on a test forum, which can be put in a folder, for example, nyvtec.com/test and do all testing stuffs there before you do real things to nyvtec.com.
   
2. If you do not have a backup for nyvtec.com (please recognize this is a very bad practice), you can also clone current modified nyvtec.com into something say, nyvtec.com/backup and try 'clean up' nyvtec.com/backup by removing users that you added from ctvtec.com
   
3. Before doing any 'JOINING' of these two sites that you intend to do, a safe move would be make sure the two sites have the same setup (vbulletin versions, addons, custom fields).

Hope this help.

Update:

Well I took a look at your two sites. Looks like you actually want to clone ctvtec.com into nyvtec.com where existing data of nyvtec.com is not important. If that is true, I would like to suggest that:

1. Backup nyvtec.com files and database.
2. Remove nyvtec.com live files and database
3. Copy everything from ctvtec.com to nyvtec.com to make it work as a duplicate.
4. Remove articles, photos and posts of nyvtec.com from its admincp
5. Update/Upgrade nyvtec.com to newer version if you want.
