SAP GUI 7.3 - Error calling up user interface components

Hi,

I just recently upgraded my GUI to 7.3 to try the new Corbu theme, but after the update transaction /SAPAPO/SCC03 to display PPM is throwing an error saying "Error calling up user interface components".

Is this something that I can correct from GUI side or does basis have to correct it at server end?

Regards,

Vinoth
