I am using my laptop to work with my sds100. The Butel opens and seems to function correctly. I can sign in to RR on the same laptop on a separate page. When I attempt to access RR through arc536pro I get the error, INIT no good, check firewall. I use Norton. The laptop I'm using I bought used and have not located any other Antivirus software. I realize this can be tedious with many different possibilities. Just curious if anyone has experienced something similar to this. I'm looking for a step in the right direction, as I am not very computer savvy. Any help would be greatly appreciated. I'm at work and won't be able to actually try anything until this evening. Thanks again, John.
