pdflatex error: pdflatex.exe(file mathkerncmssi8): Font mathkerncmssi8 not found

I am an inexperienced latex user and try to create presentation file with beamer for the first time.


But I am having issues with running beamer files from TeXnicCenter.


For example, I got the following error message in one run:


Trying to make PK font mathkerncssi8 at 600DPI..

The METFAONT mod is : ljfour

Running miktex-makemf.exe..

Sorry, but miktex-makemf did not succeed for the following  reason:

The mathkerncssi source file could not be found.

...

Running miktex-makepk.exe...

sorry, but miktex-mkepk did not succeed because PK font mathkerncmssi8 could not be created.

....

Fatal Error occurred. No output pdf file produced!


Other  experiments also give similar error messages: complaining about  "mathkerncssi source file?" could not be found!!


Any help will be appreciated.
