Getting "Cannot install a protected application from untrusted supplie" error!!!

Hi,
I have a demo app which has a UID from the unprotected range[0xAxxxxxx]. It has no capabilties. I tried self-signing, signing with the devcert from symbiansigned.com , but still getting this error.
I have followed all the instructions specified on these pages, but still to no use:
[url]http://www.developer.nokia.com/Community/Wiki/S60_SW_installer_troubleshooting[/url]
Also the installation settings are to install All. There is no timing skew.
I am going nuts here. Any other suggestions to fix this issue?
Thanks in advance.

Date/time problems would cause an other type of error message.
This one is about UID-s. What is in your .pkg file?

Not bad after all, it seems to be fine.
However the question was about the .pkg. (I was planning to ask about the .mmp later)

I am pathetic, my state of mind does not seem good :)

That backup_registration.xml in the last line, it goes to a different folder than what the UID allows.

Commented out that .xml line and its working.
Thanks a lot for the kind help. :)
