This happened to me as well last night with a program that I use. I think it has something to do with login authentication, I suspect that since they added the potentials to the screen that they need to check the user to see if they have access to potentials and in doing that nerfed my program. I tried sending the user name and password in the command line with no luck.
Interestingly, it works on my computer in the office, so either something changed overnight or there is something different between the two computers -- I suspect the latter, but don't know what to look for.
edit -- just saw Carson's post. I checked my other computer and it is working now as well.
