I have been able to clear a number of issues by turning on debugging like Gavin suggested and reading through the error logs in /webwork2/tmp/ImageGenerator.xxxx. I also looked at the troubleshooting guide that Mike sent the link for, also very helpful. Thanks to you both.
I am not longer seeing errors in the /ImageGenerator.xxxx directory and when I log into my homework set, I dont see an error there either where it lists all the problems. I was missing preview.sty, so I had to install preview-latex, which seemed to take care of a lot of issues.
I am still having some display problems though. I am viewing a homework set called MAATutorial. Some of the problems load fine, others are giving me errors like this:WeBWorK Error
WeBWorK has encountered a software error while attempting to process this problem. It is likely that there is an error in the problem itself. If you are a student, report this error message to your professor to have it corrected. If you are a professor, please consult the error output below for more information.

I also realized that I can not open the 'equations.dvi' file in /ImageGenerator.xxxx. Does this mean Latex is not properly installed? I do not get any errors when I run 'pdflatex check_latex.tex' from the /bin directory. I also no longer have errors in latex.err. On the left side of my site I have the option to change my display to LatexMathML (As well as several others), which doesnt seem to fix anything, but looks like I can switch over without a problem.
Thanks for any help with this.
