Serious problems with Episode One

[Polaris]

First: I have retail of Episode One installed and registered on computer without connection to internet. Intro looks good but in game everything looks weird, missing textures, absence of walls and after one minute of gameplay scrips doesn't work. Graphics details runs on high levels and I have no problems wih other games including HL2: Deathmatch...

Are you kidding? I'm Half-Life/Valve hardcore fan very long time. I have legal retail edition! :hmph:

Beerdude26: Thanks, I'll try this but now I don't have connection to internet on computer where I installed HL2: Ep1...

yea definetly validate files. seems like your missing a lot of textures. Console notes seem to be normal.

After two very long months when I had big problems with internet, computer and almost everything I finally done Episode One. Big thanks to Beerdude26 and Pauly!
