Computer Woes

I thought I'd better let everyone know I'm having serious computer trouble. I can't seem to get connected to the internet (an error message keeps coming up). I'm at a clients home using their computer to post this. If you don't hear from me for awhile it's because I have much more limited access. I'll keep working on trying to fix the problem, however, as technology illiterate as I am, I'm not sure how much success I'll have. I suppose that's what you should expect from an almost 4 year old computer that has already crashed and been restored once, right? Wish me luck.
