ADA stopped working

Hi,
I have asterisk working fine for years and now tried the Asterisk Desktop Assistant (ADA) and it worked fine.
All I had to do was to add to /etc/asterisk/manager_additional.conf the lines bellow
[61]
secret = 61
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
permit=192.168.0.0/255.255.255.0
read = system,call,log,verbose,command,agent,user
write = system,call,log,verbose,command,agent,user

and to /etc/asterisk/extensions_custom.conf
[ada]
include => from-internal
exten => roger,1,Dial(SCCP/61)

I installed ADAInstall.exe anwsered to the server ip, user and password and it worked fine dor a week.
No it sttoped working and I cant understand why.
I haven’t changed anything but I tried to reboot both my pc and the asterisk.
I even tried to re-install ADA
Can anyone tell me what can I check?
Thanks
Roger
