AdobeLiveCycle ReaderEnablement but cannot sign in Reader

hi all

I have a pdf doc that i ReaderEnable through the applyUsageRights service via Adobe LiveCycle (for digital signatures and form fill in). The problem is that when i open the doc in Adobe Reader 9, i cannot sign - when i click on the signature tag, i get the error message:

"the selected signature plug-in failed to supply the required signature information. Expected a string object". I was wondering if there is anything that could be breaking the usage rights?

if i create a new pdf in acrobat professional 8 with a signature tag, then say 'Advanced->Enable Usage Rights in Adobe Reader', then open the doc in Reader, the signature works fine. I can't understand why enabling usage rights done from Pro allows me to sign, yet when applied form LiveCycle it doesnt work.

Any ideas are welcome, i cant seem to find the problem after hours of research!

Thanks very much.

Is your form an XDP file twith embedded PDF data as input to an operation? Apparently there is an issue documented in the release notes on this at:
