Thanks for the suggestions. I restarted my PC after messing around with a bunch of other stuff and - low and behold - it started working fine. Geeeez.
So these four engineers leave work & get into the car for the ride home but the car won't start ...
The mechanical engineer matter-of-factly states that,
"The fuel pump's broken. We'll have to get a new one."
The electrical engineer says,
"Nope, the spark plug wires are bad. We'll have to replace them."
The chemical engineer says,
"No way, it's just water in the gas. We'll have to get some dry-gas."
The computer engineer says,
"hmmm ... Let's just try getting out of the car ... & then back in."
