URGENT: Nios II IDE instruction trace not working

Hi, 

 

I am using Nios II IDE instruction trace to see instructions being executed but when i open "trace" view, i am getting following errors 

 

"java.lang.illegalstateexception: no attr_nj_ptf_name" 

and 

"no connection to nios2-gdb-server" 

 

I tried closing and opening the IDE, and also tried in different PCs to see if its specific to a system. But the problem still persists. 

 

Please help me how to get rid of this problem. 

 

Thanks, 

Amjad
