No, I am not the main computer through which people connect, and no, they still cannot connect. When I run a diagnostic on mine, it says that there is a problem with the DSN configuration.
I'm TRYING to explain to the land lady that if it WERE my computer, then the program would have blocked everything at the hotel I was just at, etc. She won't hear me. Something happened around the time when I installed the program, so of course, it's ALL my fault.
