How to give reader extensions to a form created with LiveCycle designer

Hello,

I make forms with "Adobe LiveCycle Designer ES 8.1" and then I give them somes rights.

I use the link http://172.16.1.35:8080/ReaderExtensions/index to give my forms rights, like (Basicform filling,Import and exportform data, Submitoutsidewebbrowser, Digital Signatures)

Since 2 weeks, this link doesn't work. I called Adobe Belgium and give them my licence key and they couldn't help me becasue they sayed that it's an old application.

Can someone help me please, it's an emergency.

Thanks a lot.
