Connection problems with CDMA workshop and gs3 topic

So I'm working on unlocking my Samsung Galaxy S3,and I had it working just fine, got the MSL code and was able to get into the menus.

Now it seems that no matter what computer I use, the phone won't respond. I've checked com ports, made sure connection settings were right, but no luck, even with a clean install of CDMA workshop on a new computer.

Anything come to mind that I should double check or do to try and resolve this?

I'm going from sprint to page plus.
