Do you see any error messages when you open the console with Shift+Esc while running the map? Which kind of video card do you have, and what are the rest of your computer's specs?

Error Vertex File for 'props_c17//door01_left.mdl ' checksum 972034250 should be 1322821420

I should have come back two years ago. I gave up back then. Now, I wanted to use the map on my new computer but the problem is still the same. I saw this in the console: Failed creating font 'csgok'!
Failed creating font 'Clear Sans Medium'!
Failed creating font 'Trebuchet24'!
Failed creating font 'ChatFont'!
Failed creating font 'DermaLarge'!
Failed creating font 'Clear Sans Medium'!

Redownloading all lightmaps

That's what appeared when I started the map.

What are the specifications of your current and previous computer?

If I use windows, how do I check that? My new one is the same as the old. Just a new harddisk. :)

Think it’s this: 00262-50707-66011-AAOEM Intel(R) Core(TM) i3-4005U CPU@ 1.70GHz 1.70 GHz 16,0 GB 64- bit operatingsystem, x64-based processor.

I'm mainly interested in your graphics processor. Sorry, I should've been more specific :)

You can find out by opening the start menu and typing in 'dxdiag' (if it doesn't show up, hold the Windows key and press R, then enter it in the window that pops up). Doing this will open a window that shows some diagnostic information about your computer. You should be able to find your graphics processor model by looking in the Display tab. It'll probably have NVIDIA, AMD or Intel in its name.

♥♥♥♥♥♥♥♥♥ I'm sorry I completely forgot to report back after all these years. I got a new pc that fixed the issue a long time ago but had forgotten about this post by then.

I don't know what was in my laptop back then. It was an old Dell that I got for free from a font that helped Autistic people in homes.

Now I live on my own with a Desktop PC and what it has has no issues with the map. :)

Sorry it had to take so long, I feel kinda bad about it.
Just wanted you to know it works now and has for a while.

Hey, no worries! I'm glad to hear it works fine now.
