Mark,
Don't panic... yet!
It sounds to me like you've used too much cleaning solution i.e. your lens cleaning tissue has been too wet. I find I get streaks on lenses in this case. Try using just the smallest amount on the tissue, the idea is to have dry parts of the tissue to absorb the cleaning fluid as you go (at least that's how I think of what's happening).
If the lens is wet after you have wiped it, you will get streaks in my experience.
