Source Film Maker Surfaceproperties.txt Error / Fail To Start

[80HighDef]

About an hour ago, source film maker was working perfectly. Then I closed it to play a game, and when I returned I was given this error:



Unable to load surface prop file 'scripts/surfaceproperties.txt' (referenced by manifest file 'scripts/surfaceproperties_manifest.txt')



This error occurs after I launch the sdk, then launch a custom mod containing dota 2 files.

If I don't launch the SDK first, I get this error:



Dota\gameinfo.txt is missing



I have fixed this error before by re-installing source film maker in its entirety, but this error reoccurred so quickly that I don't really count that as a solution.

I have been searching for an answer for a week now accross google and have found nothing. All help is appreciated, and thank you for your time!

have you tried just launching SFM as the default mod (usermod)?

a missing gameinfo.txt is usually fixed by launching the sdk. dunno about mods as I never use them. I do have my dota stuff in a separate folder from the usermod folder, but it's all still part of usermod. I just added an extra line in the gameinfo.txt file in the usermod folder.

Thank you for the fast responce!

Strange, when I first encountered this problem a week ago, I remember Usermod having the same issue, but this time it works fine. I shall try what you say about adding the extra line in the gameinfo.txt file, hopefully that works.

Again, thanks again!

Edit: So far, so good. I will reply to this post if this issue continues.

What about surfaceproperties.txt? My SFM occured same error. I must fix it. SFM is sometimes hard to use because of errors..
