When I have a problem I will usually try at least two things
1--Start off as if this is the first time time installing it by just going over every entry, delete what's there and then reenter the required information.--THEN
1-Shut the computer down, not a reboot but a complete fresh rerestart from off to on.
or
2--Uninstall the unit--complete-- as if it never existed. the reinstall from scratch
Often I'll Google the problem knowing that you can't be the one one who experienced it, Many times there are numerous or similar examples of what you are experiencing. Quite often I find enough information to help with a good result.
