Read Report - Error ED800 Code is protected

Hello,

we have some Abap Code from a supplier that is protected (with se38 you just get the error ED800).

The error occurs because "read report" results in sy-subrc <> 0.

Reposrc and PROGDIR looks good. SQL-Trace shows the access to Reposrc.

Any Ideas how to see the Abap Code ? The ABAP itself is running fine... Only the includes are protected in that manner..

It seems almost the same protection like used in SAPMSYST.
