You have set Document->Settings->Post Script Driver to "none". Set it to "default" and the file will compile.
Thanks a lot Juergen, now the figures work fine, but I have 2 new problems: 1-it cannot read the superscript fonts (for example 10 to the -10 as superscript)it says: Undefined control sequence x 10$^{\text {-10}}$ mbar) is equipped with a variable-temperature The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined. 2-It has problems with the references (in one part of the document I put many references from a bibtex library, natbib (numerical)...it is working in the rest of the document, but not the part that has many citations. I get the following TeX capacity exceeded, sorry [input stack size=5000] ...ü2002,RSM:Bö99,RSM:Bö99a,RSM:Wec2001a} (Figure If you really absolutely need more capacity, you can ask a wizard to enlarge me. Haw can I enlarge it? Thanks a lot! M.
