That error code 0x57 is the general error returned when an exception of any
sort occured in the CSP code. That can include bad pointers, arithmetic
overflows, debugging breakpoints, and of course, not properly saving the
value of ESP across a function call.

Do you have libraries or external DLLs you call in your CSP? Verify you are
using the correct calling conventions for each of them. Try running IE
under the debugger when enrolling a certificate, to see if it can catch the
location of the exception.
