I encounter thsi problem while signging this PythonForS60_1_3_22_3rdEd_unsigned_freedevcert.SIS to www.symbiansigned.com website using OPEN SIGN.

Code:
FAILURE: Submitted .sis file uses a UID that is not allocated to the account holder matching this email address (0xf0201516 )
I know the meaning of it, but how can I work around it? I want to sign it under my development purpose UID.

Please help.
