Unable to work with BIRT after upgrade to RTC 3.0

Hi,
Our RTC server and clients were just upgraded to 3.0. Since then I can't work with birt (the perspective is not loaded properly).
I tried upgrading the needed components to the following versions (after reading about it in the forum), but still no success:
birt-report-framework-sdk-2_5_2
dtp_1.7.2
emf-xsd-SDK-2.5.0
wtp-sdk-R-3.1.2-20100211202452

Can someone give the exact needed components (with their versions) which are needed in order to run BIRT on RTC 3.0 ?

Thanks,
Tal

Yes me too. I followed all the directions in the wiki but still I get an error (a warning actually) that "The opening design file is not a valid design file or the file does not exist"
Then when I hit OK on that I get the 'XML Source' tab displayed but clicking on any other tab throws an error;
"Error in XML Source Page must be corrected before other pages can be used."
This is creating a new blank report.

This is the XML that is shown;

I have found it has something to do with using my existing workspace.
If I create a clean project, I don't see the issue and the XML is identical.
I guess I'll create a new workspace.
