Do you by chance have Java 7? Java 7 is known to cause many SMART related problems, which is what you have here. Heres a quick guide by YOHOJO on how to downgrade to 6U32. I used to have the same problem, downgrading worked for me.
1) Completely remove and delete all Java from you computer. I THINK the regular ol windows uninstaller should work just fine, but I prefer to use Revo Uninstaller (free program found here
http://www.revouninstaller.com/) which COMPLETELY removes every trace of the program. Choose advanced uninstall and delete every damn little thing it lets you (be careful, it may ask you to delete some programs you want when deleting java so READ before checking boxes).
2) Even after doing these things, go to C:\Program Files (x86)\Java and delete any and all Java folders found in there!
3) Install Java 6 Update 32, 32 bit version NOT 7 for me, they are found here

You should just have to download JRE, but I got JDK (which includes JRE with it).
