Thanks. I took the advice and downloaded SR 2.1 (it took well over an hour). It appears to have solved the problem. Still it would help if CL's website made it clear that they no longer use a challenge code/response code format (they still have a link somewhere on the site) and that the info in the manual is wrong. I'm sure I'm not the only one who was frustrated by this. Not a good way to create customer loyalty.
