Your problem looks like a crash. If it is the case you may find a log 
file (under linux the name is something like hs_err_pidXXXXX.log).

I don't think that reinstalling the software will improve the situation.

Problems with plot are often related to graphics issue. Have a look at 
http://wiki.scilab.org/Graphical_issues_with_Scilab_5.0. There was a lot 
of messages on similar issues so you may have a look at the mailing 
lists archives...

Another possibility is that you run out of memory (because you launch 
the code several times). In this case you should try to delete variables 
that are no longer needed.

Sorry I cannot help you much,
