Server plugin

Hi!
Today I run my RM EAP 96.552 and see the login prompt from IDEA Server Plugin. There was an error "connection timeout". I skip login and during startup process is get many alert windows, mailny about recreation of config files. I restart my RM and again aletr windows. I distable/uninstall plugin, restart RM and aletrs still are displaying during stuartup. Also during work alert window "Cannot save sceme 'Default: incorrect header check". It is quite confusing getting alerts on every startup.
O use Mac OS.
