Mutantbunny,
Please try this debug version. To run, double click on LEDebug.bat. Hopefully, it will generate a log file, LEDebug.txt, which you can then attach here for me to check out. It's just a normal text file, so you can look at it if you like.

I say "hopefully" because I'm still not very familiar with .NET... it works on my machine, but there's some (slim?) possibility that it won't on yours.

By the way, there's no use in anyone else downloading this... it's been crippled and won't do anything except show you what it's trying to do. Of course, if you're interested in seeing the extent of work that the LotExpander does, then I suppose you can try it.

[Update:]

Test version removed. No longer required.
