Basically I had to reformat my hard drive, and in order to do that I copied all the files from it to a disk image which I then used to restore through disk utility.

Now this worked as far as individual files go, but the OS for some reason didn't copy properly. After restoring from the image, the machine started up with an infinite pinwheel and apple logo, not going anywhere, so I eventually just reinstalled snow leopard from the original installer. This is fine as far as the system itself goes, but I'm having some very annoying issues - for one, some things which I had registered have reverted to trial versions (probably just a question of moving some preference files from the backup which got overwritten, shouldn't be too hard) but far more seriously, a bunch of kext extensions aren't loading, including one which is needed to run my external wifi antenna (the internal one is banjaxed, won't connect to any network unless you're sitting beside the router at all times).

 

Here's the console log. Why are these kexts not working, when they worked perfectly before the reformat? Still struggling to understand why copying the entire root dir to a disk image and then restoring from that image did not, as expected, yield an identical system, and why I even had to reinstall after doing this. But more urgently, how do I get these extensions working again? Using airport isn't sustainable, I can't sit on the stairs every time I want to use the internet

As you can guess, Ralink USB Wireless Driver is the one I'm having trouble with, although the other error you see, BoomDevice, is one of the apps which had been registered but has reverted to trial. The errors in console made me think it was a permissions issue, but repairing permissions, despite taking half an hour and modifying tons of files, did not resolve this issue.

 

How do I fix this, and also out of interest, why did it happen in the first place? I imagined formatting and restoring would be far, far less complicated than this O_o

 

EDIT: Should point out that obviously going from 10.6.8, the reinstall reverted to 10.6, and I haven't been able to upgrade since I can't get this internet kext working. Shouldn't be a problem though since the wireless driver was for 10.6.x...
