The most common cause of this problem is that you upgraded from R 2.15.x to R 
3.0.x without upgrading RKWard as well. You need at least RKWard 0.6.1 for 
that, and it has to be a build of RKWard compiled against R 3.0.x. We don't 
know, what system you are running, but if it is e.g. Ubuntu, suitable RKWard 
packages can be found at https://launchpad.net/~rkward-devel .

If actually, all you did was installing an additional package, then apparently 
your installation of R somehow got broken in the process, and now it will not 
start up properly. Start a plain R session from a terminal / console, and look 
out for any error messages. Try
  library("rkward")
to see if the rkward R library can still be loaded. If in trouble, run
  sessionInfo()
in addtion to that, copy-and-paste all the output, and most likely we can 
point you to a solutoin.
