Thank you again for such promp replies.... Here is what has happend now.
I'm basically at the same point after hours of doing all I can think of. I have totally uninstalled everything and re-installed Vengeance, BK, and Mercs again. I ran the PR-1 patch, installed the 2 MekPacks, and installed a few maps packs like NewBettlefields. There are NO variants installed or created at this point. I then copied the Mercs folder info to the new folder - MercsMod. I ran the weaponspack2 on that new MercsMod folder. It installed perfectly, so it seems to have worked as it should at this point. I went online and the only servers that show up are "newer" than my version, so I can not joing them. My version showing is - 51.00.00.0002. The version of Mercs without the weapons pack is - 50.07.01.2105
Weell, this is what I have been able to do everytime and I'm confused. The full WeaponsPack2 installs perfectly each time, but then none of the servers will let me connect to them as they are showing up as "newer" versions??? So, it looks like I need to install the additional patch - weaponspack2(1), to upgrade to a yet newer version. But when I try running the weaponspack2(1) patch it NEVER will install and I get the errors as listed above in my previous messages??? Does this make sense.
Do I need to install the WeaponsPack1 first or instead of WeaponsPack2. If so, where is WeaponsPack1. I searched the site and can't seem to find it. Sorry if I'm blind!

Thanks again for all your help.
