I have a problem... ..
In almost every map I have this same problem, but now I'm talking about TFV-mappack. I have downloaded and extracted the files to C/Program Files/Steam/Steammaps/atsu/portal/portal/maps
In the game at the bonus maps and load bonus maps (or whatever it is in english) I cannot load it, becasue is shows me a folder (The Flash Version Mappack as I named it) and there are the 4 files. I have no place to load the maps and I cannot load the map from the console (map mapname). Hwo can I get it work? ..

I have the same problem in most custom maps, I have got only PKM4 and some other maps to work.

Sorry a bit messy explain and bad english.

pelin asennuksessahan on voinut tulla joku virhe Ett? kannataiskohan sun asentaa koko peli uudestaan ku ei tolle oikee mit?? muuta ymm?rrett?v?? syyt? l?ydy. Koita tota jos muu ei auta ja sano sitten l?hteek? toimimaan.

(I speak finnish, so don't get embarrassed, you other guys )

Oke, m? koitan sit?. Toivottavasti toimii. Tii?tk? l?hteek? Achievementit/saavutukset pois ku asennan uudestaan?

Penapappa told me to reinstall the whole game. I'll try it. Do you guys know will all of my achievements be reset?

No, the achievements won't be deleted. I believe that they are saved on Steam

its also possible that you are not infact supposed to install to the "maps" directory, but to the directory above that (usually C:\program files\steam\steamapps\USERNAME\portal\portal) because alot of mappers have more than JUST the map files (.bsp) and therefore need to disperse their files into more than JUST the maps directory.

I'll try the JUST thing too. :p I have tried steammaps/atsu/portal/portal/The Flash Version Mappack too, I'll try to met it JUST. Haven't reinstalled yet tho.
