Error when Opening NDS

Hi All,

I have a very strange problem with my NDS.

When i click on NDS icon it gets opened shows all the views in the View layout and then I get a pop up msg saying there is an error in log file and it saves the workspace and closes by itself.I have checked in the log file. Its showing some project which is closed as of now.

But NDS was working fine till an hour ago and suddenly it got closed, and when i try to restart its not getting started.

My NDS is 2.16 version.

I have SP16 J2ee server installed.

Can any one tell me whats the problem?

I tried copying the Plugins folder thinking that there would be some corruption in that but it did'nt work.

Pls do let me know how to proceed.

Thanks & Regards,

Sirisha.R.S
