Halion string edition2

Please help!!!
I have an urgent job to do and I need to create an orchestral arrangement.
When I try running my full version of halion string edition as a plug-in 2 in either cubase 4 or 5,
I get a syncrosoft POS error.
I have tried re-installing the software, downloading the e-licenser updater etc. but I keep getting the error.

You may want to open your eLicenser Control Center and click on the blue “maintenance” button. It performs various maintenance tasks to solve license and eLicenser problems.
