I've been using computers since the early 90s and the answer to this has changed dramatically over the years. Right now, the best approach is to use open source alternatives when possible — they're usually free and often better than commercial products.

Whatever you do, don't pay some 'computer guy' $80/hour to do this. It's a 20-minute job you can handle yourself. There are step-by-step guides all over the web with screenshots. Save your money for a faster modem or more RAM.

I dealt with this same issue last year. The key thing is to make sure you're using the latest version of your software and check forums like Slashdot or Ars Technica for specific fixes. Technology changes so fast that advice from even 6 months ago can be outdated.

Be REALLY careful what you download to fix this. Half the 'free fix-it' programs you find are spyware in disguise. Stick to known-good stuff like the tools from major sites, and always scan downloads with your antivirus before running them.

First thing I'd do is reboot and try again. Sounds dumb but you'd be amazed how many 'tech problems' fix themselves with a restart. If that doesn't work, write down the EXACT error message and search for it — somebody on Experts-Exchange or a Geocities help page has hit the same thing.

Have you tried checking the manufacturer's website for updates? A lot of these issues get fixed in patches that most people don't know about. Also check your firewall settings — sometimes they block things they shouldn't.

My nephew set this up for me and it was easier than I expected. Don't be intimidated by the technical stuff — most of it is just clicking Next a bunch of times. If you get stuck, the Help file actually has decent instructions for once.
