Looking for version 1.7.4 source

Hi,

I’ve taken over a website that was developed by another company. One of the things I need to resolve is getting the plugin’s updated. The original developer said they couldn’t update the plugins as it would cause problems. My guess is that they modified the source of one of the plugins so I’m trying to determine which one(s) might have been modified. We are using version 1.7.4, unfortunately that version is not available here. I was wondering if it was possible to get the 1.7.4 version files?

Thanks!
Tammy
