There are a lot of files that when I try to dl, I keep getting 'attachment.php' files instead of the zipped game files.

Is there any reason this is so?

Which browser you using...
I myself faced this error...
Renaming the php file to zip/rar solves the problem...
Also clear cookies and see if the problem gets solved...

R u using download manager? sometimes this caused by download manager and browser compatibility problem.

Yeah, I use Firefox browser. this could be the reason.

Make sure u didnt use any 3rd party download manager. Just use the standard firefox download mgr.

Make sure u hover on the attachment link then left click it. Dont use right click > save link as..

Can someone tell me what's going on with the forum. I've been gone a week and I come back and the form is different.

Use Internet Explorer and there will be no problem.
