Hi Guys,

Had a motherboard failure on my laptop and lost my login/server details, bought new laptop, so needed to install SC and make data connection again.

I had a look at the self help section but not sure how to do it all, selected Rithmic but the server list is blank....i was on Chicago aggregated Apex server last time i think.

thanks.

Update.

I got the server list working by clicking OK. I put my rithmic account number and password in but it still won't connect to the Rithmic chicago server. i tried aggregated & non-aggregated servers
