...failed to find an appropriate PIXELFORMAT

Try creating/modifying a shortcut - where "target" is listed, add "+seta r_mode -1 +seta r_fullscreen 0 +set r_customheight <screenheight> +set r_customwidth <screenwidth>
where <Screenheight> and <screenwidth are your screenheights and widths desireable of course.
Use a common number like 1280x720 or 1024 x 640 or so, they have to be multiples of 4 afaik. Make the numbers smaller than your full screen resolution, because "r_fullscreen 0" actually forces you into windowed mode.

That means you're setting your screen resolution to 640x480, which is rediculously small. Well, it's actually default for trem 1.1 vanilla (2006), you probably want a newer client. I have a list of updated clients here: https://sites.google.com/site/zdrytchx/
Select a 1.1 client of your choice. I personally use tremfusion, the only buggy thing about it is playing on impure servers where your ui is bugged but there aren't that many impure servers available, and you can always download a custom ui file to fix this problem.

Also, are your graphics drivers "up-to-date?"
