But the weird thing is that when I tried the same script earlier in the 
day, it went through about 200+ links before encountering a situation 
that my script didn't handle. But now when I get this latest error that 
I posted, it's only going through about 150 links before stopping.

Interesting! That's good news, and I'm glad I didn't spend hours trying 
to use one to solve it! :)
