OK great now everything build ok.

Next step: write a screen scraper. First I wanted to use Solvent, but
IMO it lacks a good tutorial, so I started to follow the directions
given at:

http://simile.mit.edu/piggy-bank/screen-scrapers-howto.html

But then apparently I did something wrong:

Yes, apparently I messed up the regexp syntax a bit. Now the problem
is that I'm now completely stuck with this error: reloading the .n3
file has no effect (it keeps throwing the exception). Even
de-installing and re-installing Piggy Bank doesn't clear the corrupted
file. And I've checked in the Application Data's extension directory
for a "scrapers" folder, but I didn't find such a thing.

Please, how do I get rid of this error?
