LaTeX Why Does LaTeX Show Invalid for Simple Math Inputs?

[HallsofIvy]

I'm back! My fiancee's computer went down after an electrical storm. (She had it plugged into a surge suppressor but there was a lightning strike within 100 yards. Apparently it was not suppressible!)

Anyway, now that I am home I see that my LaTex always gives "invalid" even for something as simple as [ tex ]\theta[ /tex ].
\theta[/itex]<br /> <br /> Any one know why that is happening?

Testing 11

<br /> \sum_{n=1}^{\infty}\frac{\chi(n) }{n^{s}}=\prod_{p\in\mathbb{P}}\left(\frac{1}{1-\frac{\chi(p)}{p^{s}}}\right)<br />

And testing inline:

E = mc^2 \textrm{some long junk, too}

and

a=b

Testing trim 3...

<br /> \sum_{n=1}^{\infty}\frac{\chi(n) }{n^{s}}=\prod_{p\in\mathbb{P}}\left(\frac{1}{1-\frac{\chi(p)}{p^{s}}}\right)<br />

And testing inline: E = mc^6 and a=c=m=d
