Not able to build watchface

This happens with Samsung examples, I haven’t even tried with own designs anymore. I tried to uninstall the program, deleted my old certificates, installed the program, changed the WiFi, connected my watch and got new certificates. Nothing helps. I went through exceptions in my firewall, and there were both sdb and Java.

I get this error message in eclipsec.exe:
error: failed to get status of ‘C:\Users\paivi\GearWatchDesigner\keystore\device-profile.xml’: No such file or directory

Is there an issue with my certificates? I do have both certificates in the mentioned folder. Should I try to delete them once more?
