I have the MS Digital Imaging 2006 program and it's probably similar to the one you have... It really isn't a "bad" program and is fairly simple to learn although it usually doesn't come close to Photoshop's offerings in the market. It's also dirt cheap in most cases...
My suggestion is to start over with your picture(s) and just try again before you decide to go out and buy another photo program. Not saying you can't or maybe shouldn't upgrade to Photoshop eventually but what you're trying to achieve can be done in almost any photo program with good results (except by possibly me who seems to be electronically challanged when it comes to computer stuff

).
Just try again or even several times again before you give up on the project. You'll get it...
