I installed Dude beta 17 and spent a couple of hours manually seting up a map with about 25 hosts. Everything was working fine until I started to add another host. While I was adding the host, Dude stopped responding properly, so I shut down Dude and restarted it. Now Dude server starts up but I can’t log into the local server. With Dude server running cpu usage stays at 100% If I reset the config, it logs into the local server just fine. Have any ideas how I could fix this problem and save the time I spent on my config? I sent a zip file of my data folder to support, but haven’t recieved a reply. Thanks for any suggestions! 
Hi,
I am experiencing the same problem.
I sent to support@mikrotik.com the config files of my DUDE.
regards,
pease upgrade to beta18 and check how it is working.
just a “me too” to this thread.
I have tried both versions from the website (2.2 and 3.x) and both will consume 100% of my cpu.
Not sure if it matters or not. But in task manager I always see 2 dude.exe’s running.
