Can somebody help me with the Sierpinski Base 5 project please?

I have done a few workunits on it back in 2007, and it went well at the time, and now I tried it again but I am seeing no results coming up in the stats after two days of the machine running.

It had been a long while since I last crunched there, so I figured I should get the latest clients all over again, create the configs and stuff and start crunching.
I went to the mersenne forums, where all the maths projects are located and on their subforums I found what I thought would be the latest-and-greatest of the client applications...

I downloaded all the necessary parts... PRPNet and pfgw, configured the thing the best I knew how, and it has been working for two whole days, downloading and testing candidates and sending back the results...

...but nothing comes up in the stats pages, for me, or for the team!

I am now wondering if the "server" line in the configs may not be right... but if it's not, how come it is sending me work and gathering my results?
server=SGS:100:50:prpnet.primegrid.com:12000
...and in that case, where are my results going to?

Is anyone running this or knows how it is configured, that can help me please?
