I was using my server yesterday no problem. Came back today with an error when starting the server
runnerw.exe C:\Ruby187\bin\ruby.exe -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) "C:/Users/Stefan/RubymineProjects/gallery/gallery-app/script/rails" server -b 127.0.0.1 -p 3000 -e development

=> Call with -d to detach
=> Ctrl-C to shutdown server

Not sure what could be causing this and it's baffling me why its only now decided to pop up.
I was able to fix this by reinstalling the actionpack gem. It must have got corrupt or I accidently changed it between last night and today.
