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.
