Did the debugger jump to any source code?
What does the "Callstack" window show?

If neither shows anything, the error might be in the RTL or kernel. What 
does the assembler win show?

Give the data from the error message, I guess there is a nil pointer 
deref (e.g. access to a field in an object that is nil)
