UMAT subroutine

Hey guys,      

               I'm new to using subroutines. I have installed the Intel Fortram Complier v10.1 and using it for running the subroutine UMAT. I am first testing the umat subroutine for Isotropic elasticity as given in the abaqus manual for a single element with one integration point, but I'm facing the following error:

Unexpected error 193

12/6/2010 2:14:08 PM

Abaqus Error: The executable D:\SIMULIA\Abaqus\6.10-1\exec\standard.exe

aborted with system error code 5.

Please check the .dat, .msg, and .sta files for error messages if the files

exist.  If there are no error messages and you cannot resolve the problem,

please run the command "abaqus job=support information=support" to report and

save your system information.  Use the same command to run Abaqus that you

used when the problem occurred.  Please contact your local Abaqus support

office and send them the input file, the file support.log which you just

created, the executable name, and the error code.

Abaqus/Analysis exited with errors

Well I'm stuck here and see no way out of this. Please help me. Thanks in advance.
