Problem while integrating crucible with Jira

[Nilanjan Sen]

Could not retrieve manifest from http://neilsen.atlassian.net. Please check the JIRA Server URL, and ensure it is JIRA 4.3 or later.
Please see the Troubleshooting Guide for more information.

Please help me out

FYI I am using trial version for both JIRA and Crucible.

Have you created Apllication Links in both Jira and Crucible successfully??

I am getting that kind of error too!

Crucible 4.5.3 x64 + Atlassian JIRA Project Management Software (v7.5.4#75010) 

Any ideas how to resolve this?!
