I am submitting a paper at CIKM. So I have downloaded the sig-alternate.cls and sig-alternate.tex files. But problem is that while compiling them the following errors are coming:

******LaTeX Font Warning: Font shape `T1/aett/bx/n' undefined
(Font)              using `T1/aett/m/n' instead on input line 414.**
...
LaTeX Font Warning: Some font shapes were not available, defaults substituted.****

I am not getting any clue to fix the error.

The warning says that the font T1/aett/bx/n (font ae monospaced bold) was unavailable (it doesn't exist) and that instead LaTeX used font T1/aett/m/n (font ae monospaced). The ae fonts are based on the default Computer Modern fonts, where the monospaced version has no bold; these fonts are loaded by default by the sig-alternate class.

Basically, you can't have bold monospaced text with this set of fonts because this particular font doesn't exist.

As Werner commented above, a solution is available at this question.
