I looked a little bit yesterday, but wasn't seeing the SCLogin module popup working in either site properly (they both had different issues). It looks like you've switched to another modal popup module now.
I'm sorry we could help you get it going. Should you wish to come back to the SCLogin module, just let us know. We'll gladly help investigate further. It's likely a Javascript conflict of some sort, we'd just need to narrow down the cause and develop a fix.
Thanks, and best of luck,
Alex
