If you encounter any problems with TeX or LaTeX then you should first consult the documentation and the TeX Frequently Asked Questions list maintained by the UK TeX Users Group. There's also A Visual LaTeX FAQ by Scott Pakin: a PDF document presenting examples of customized LaTeX formatting and formatting problems, hyperlinked to appropriate pages in the UK TUG FAQ. A german FAQ list is maintained by the German speaking user group, DANTE.
Alternatively, the solution may come up on the comp.text.tex news group. If this doesn't help, you should find out if there is a local TeX mailing list or TeX guru who can help you. If you've still got no joy then you should either post to comp.text.tex or contact the TeX Users Group. Alternatively, you may have found that rarest of beasts :-) a bug with LaTeX for which we ask you to send in a bug report.
We are sorry that we do not have enough resources available to offer any assistance in installing or using LaTeX.
