Local scan crashes MP (1 Viewer)

[WsQ]

Got a new problem, whenever local scan occurs, I get a Windows message that MP has stopped working and has to be shut down. Odd thing is that MP seems to be working fine. Anyway I have to click ok on the message to make it go away and that shuts down MP.

This all started today after everything working fine yesterday.

Log attached.

Seems like the cause is a regexp rule I had created.

Could someone help me to get this fixed.

(?<series>[^\\$]*\.((19|20)(\d{2})))\.(?<season>(\d{2}))\.(?<episode>(\d{2}))\.(?<ext>[^.]*)

EDIT: For example for file Conan.2011.06.29.Liv.Tyler.HDTV.XviD-DAH.avi

Seems like I was able to fix it myself after all. I changed the code into this:

(?<series>([^\\$]*\.\d{4}))\.(?<season>(\d{2}))\.(?<episode>(\d{2}))

Is there something that I should try to avoid when I'm trying to learn to create these rules (to avoid further problems)? It would be nice to know what exactly caused the problem in the original regexp..
