Redmine

Hello,

i want to Upgrade from Version 2.3.3 stable to 3.0.0.

I deinstalled the old Installation (C:\BitNami\redmine-2.2.3) over the normal Deinstallation-Progress in the programm-Folder. i`am don´t saves old files. restarted the whole Server.

then i installed in the Folder C:\BitNami\redmine-3.0.0 without E-Mail-Settings. after this a new Installation should be working . but the 2 thin-services don´t work.

i´am searching for the solution. i tried this.

cd ?apps/redmine/htdocs
bundle exec thin start -e production

i can now accesing a Little bit of redmine. ( it warns me that "dl is deprecated use fiddle" , it is only a warning and i think not the Problem)

But i don´t know what i can do , that the thin-services become working. i have no plugins installed.
