You may want to try clearing some space on the stack. Put something like 
the following after your nops and before the payload 
itself :"\x81\xc4\x54\xf2\xff\xff" (add esp, -3500)

If this doesn't work, try replacing your 0x90's with 0xCC's and make sure 
that an int3 is trapped by the debugger.

Are there any characters I should be filtering out on the shellcode
generator or any other gotchas I should be aware of when doing this
type of work? Any help would be greatly appreciated.
