Can't test maps

[Limpet]

I've googled and searched this topic for about an hour and can't get help for this. Maybe one of you knows.

Ok so I've got my map in Hammer and want to see how it looks ingame. I go to the run map dialog leave all the things on normal, unchecked dont run map and put in -dev -console +sv_lan 1 in the additional params. It works the first time but after I closed Half life to go do something else and tried to retest my map it doesn't work.
I can't copy all the stuff that pops up in the console so I took a screenshot and found that I got a windows error:

Half Life 2 DM: hl2.exe - Application Error The instruction at "0x2406dd69" referenced memory at "0x010efacc". The memory could not be "read".

Also in the console I see:

couldn't exec listenserver.cfg

Maybe the two are related?

I hope someone knows what I can do to fix this. Thanks ahead of time.

the listenserver.cfg error is normal. Just means you're not running a dedicated server.

Ok, thanks

But I still don't know why I can't run my map. I've tried opening through Hammer and starting the game then loading the map from there but it still crashes.
