Recording doesn't work
I have spent plenty of time searching for a fix to this issue, and have found a few posts regarding it, but no solutions thus far.
I know I have a decent enough computer, that isn't the issue.
Basically, trying to learn SFM and following the Valve video tutorials exactly is how I ran into this problem.
The actual issue:
I set everything up, loaded map, work camera in place, etc.
Then I try pressing record. The usual context window comes up, but the title box for the demo is greyed out, then it lets me type in it as soon as I change another option in the window, I'm not sure why.
Then I try recording, and suddenly the game window switches to the main menu of TF2. I hear the beeps, it actually does record somehow. I know this because I just open the console in the game window and load the map I wanted to record in, and it loads the map and records, but the player model is missing still.
Additional technical information:
I checked the console afterwards, and I can see it disconnected me from the local server, saying "disconnected by user", although I can't quite identify the cause of the sudden drop.
Another thing in the console I noticed that may be related, is that it said it couldn't find the .dem file, or something similar to that. I thought this might mean it might not have write access to the folder? It may be nothing, but it seemed like something worth noting.
Steps already taken:
I've already attempted to verify the integrity of my cache, I've uninstalled the application for the moment, have not tried re-installing yet, I didn't think a re-install would be my best option at this point, since it's obvious and most likely won't change a thing, but who knows? (Attempting to re-install right now, we'll see.)
EDIT: Re-installed and, forced allowing write access to SourceFilmmaker folder and all subfolders (if that actually did anything) still not working at all.
Other pertinent information:
•Installed Steam folder onto B: drive instead of usual C: drive, as such, my directory is B:\Steam\steamapps...etc (I doubt this would make a difference, but maybe it assumes a certain folder structure? Obviously it's far from a stable program.)
•No custom content used when trying to follow Valve video tutorial.
•I've also tried using different beta (and non-beta) versions of SFM, to no avail.
