Well, there was a problem with upgrading to 13.04, and I ended up having to force a reboot on my PC, which then corrupted my entire Ubuntu OS, so I'd have to reinstall it (again). This time, I just sort of scrapped it and went with Linux Mint (15 "Olivia" (It was the most recent version with an easy Windows installer)), and now it does happen to be working, so... Problem solved, I guess ^^;
