Fatal Application Error

I'm using the trial version of the professional edition of Screen Scraper. I installed it today, and ran through all the tutorials just fine.

While using Screen Scraper I installed some updates for Windows XP, and let it restart my computer. I do not recall if screen scraper was closed when I chose to restart, but it may have been.

My computer restarted fine, but now I am no longer able to run screen scraper, when I try I get:

This Application has Unexpectedly Quit

Invocation of this Java Application has caused an
InvocationTarget Exception. This application will now exit. (LAX)

When I click the Details button I get a window with this:

java.lang.NullPointerException
at com.screenscraper.scraper.ScrapingSessionManager.loadScrapingSessions(ScrapingSessionManager.java:1159)

at com.zerog.lax.LAX.main(DashoA8113)

Needless to say, screen scraper does not open :(

I saw a post that addresses a similar problem, the solution for that was to install the latest updates (pre-release version?) for screen scraper, which I am unable to do, because I cannot open the application to go to the menu and choose to do so.

Thank you in advance for any help or advice in fixing this problem. :D
