Runtime Error! Keep on happening while using amap, anacor and ca pckg

Hi there dear R users,
 
Does anyone have any idea what the following error means and how to sort
it out?
 
Runtime Error!
Program: C\Program Files\R\R-2.9.0\bin\Rgui.exe
 
This application has requested the Runtime to terminate it in an unusual
way. Please contact the application???s support team for more information.
 
Here is the story:
Running the same code, sometimes the error happens and other times it doesn???t.
It all started while still using the old R version; therefore I looked
for the updates and its keep on happening with the new version too.
 
The packages that I am using while experiencing this continues error are
the following:
amap
anacor
ca
 
Please help!
 
Ana
