Output error in procedure

Question

I have successfuly compiled the following procedure. When I execute in SQL Worksheet I get the following error. I have tried everything I could think of over the last hour or so to resolve. Anyhelp is greatly appreciated. Thanks in advance.
Procedure: letsGetPaid.sql
CREATE OR REPLACE PROCEDURE letsGetPaid
IS
probFile UTL_FILE.FILE_TYPE;
my_feed_line VARCHAR2(2000);
CURSOR C1
IS
SELECT PROB_CODE, PROB_DESC, TEXT FROM prob_code;
BEGIN
probFile := UTL_FILE.FOPEN('C:\getpaid\output','problem_code.txt','W');
-- Construct output lines
FOR probline in C1
LOOP
my_feed_line:= (probline.prob_code) | | ',' | | (probline.prob_desc) | | ',' | | (probline.text);
EXIT WHEN C1%NOTFOUND;
UTL_FILE.PUT_LINE( probFile, my_feed_line );
END LOOP;
UTL_FILE.FFLUSH(probFile);
UTL_FILE.FCLOSE(probFile);
END letsGetPaid;
The following error message is output:
BEGIN letsgetpaid; END;
ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "SYS.UTL_FILE", line 98
ORA-06512: at "SYS.UTL_FILE", line 157
ORA-06512: at "SYSTEM.LETSGETPAID", line 14
ORA-06512: at line 1
Again thanks in advance.

Thanks, I will make that change. However the error below was generated because I had failed to make the required UTL_FILE entries in init.ora. Once I made those changes everything worked fine.
I appreciate your comments.
