SAGEPAY 3D SECURE NOT WORKING ON JOOMLA JOOMSHOPPING

Hi I have a latest joomla website and using joomshopping. I have purchased a sagepay module from joomshopping and it is working fine but 3D Secure authentication is not happening. The url is displayed but password page does not appear and it redirects to order finish. Joomshoping guys have been looking into this but they can not find any error. Here is a communication between me and sagepay customer service Good Morning Usman. Thanks for your call today and, as discussed, I have attached the log of the transaction for the Mark Robey customer. Currently we are not receiving a PARes from your system which is the final part of the 3D Secure Authentication process however if the password box is simply not displaying for the customer then it could be due to the ACS URL being truncated by your system. I can confirm that the ACS URL we are providing your system is [login to view URL] If there are any characters added or removed from the above URL by your system then the box will simply not appear. If I can be of any further assistance please get back in touch. Kind regards, Ross Caulfield Customer Services Advisor Sage Pay Okay I will need someone who can actually do this and have ability to fix the problem. The sagepay has put a block on my account untill 3d secure is fixed. I would not be willing to pay any deposit. I will only pay the money once problem is 100% solved. Let me know if you need anymore information before giving me a quotation Thanks
