Errors with Lyx 1.2.1

[Hoffmann, Rainer]

After processing a Lyx-Document which worked fine under Lyx 1.1.6 in Lyx
1.2.1 I got three error messages right at the beginning of the document
which I can't understand:
1) Missing $ inserted
\begin{document}

2) Package babel error: You haven't defined the language american yet.
\select@language{american}

3) Package babel error: You haven't defined the language american yet.
\select@language{american}


Can anybody please help me to get rid of these errors?

Thanks,

Rainer
