Windows 7 - Problems with Canon MX420 Scanner -- Where do my files go?

Okay, so this hasn't been a problem for me before. Just yesterday I was able to scan documents to my PC; however, today it is causing me a lot of trouble.

The way I usually did this before was by going to 'Start' --> 'Devices and Printer' --> 'Canon MX420' --> 'Scan Management' and then I could scan my pictures.

But today, my "Devices and Printers" are not even showing up at all! It just keeps on loading and loading and loading... I have been at this for almost an hour now, but still they are not showing up.

So my next step was to go to my Canon MX420 scanner settings. Once I got there, I tried to set my files to go to a certain place. However, the only settings they have is to open up the scanned document in Photoshop CS3... But once that opens up, the document is not even there!

I really have no idea what's wrong? I mean, this was working fine yesterday but all of a sudden, it's so messed up. If someone could PLEASE help me, I would really really appreciate it!

I found an alternative to saving the scanned documents to my PC. So it's all good for now.
