Cobian for Backups-Anyone here familiar with this?

I'm trying to install and use Cobian for my backups (each time I use the Win7 backup, it comes up with an error whose solution is a bit more complicated than I want to tackle). However, I keep getting an error that my login was faulty.
I've tried different names, different passwords. I don't use a password to get onto my computer, so I just picked a random one. I've installed and reinstalled so many times I'm just about to throw in the towel.

Is there someplace where I can find DETAILED instructions for installing Cobian V.11?

Or does somebody know what I'm doing wrong?

Is the installation video on their website any help?

They also have a text version

Thanks, Jenny, for the links. For some reason, this is the second video for Cobian that I've found that I get no audio for!
I have audio for everything else I do on my computer--games, snippets of news, etc, but not these videos.

Anyhow, I don't have much time to devote to this right now, but I see that I must install the program as "administrator"; I haven't done that so when I get some time, I'll try again and hope that makes a difference.

Thanks!

Okay, this was weird: I went to submit my reply and was thrown out to a screen that asked me to log in before I could submit my reply. Only one problem: I am always logged in! Hmmm. Well, did what I was asked to do and was able to post. Strange.

I don't believe there is any sound -

Well that solves that puzzle; thanks Inland!
