Install configurations by double-clicking them, not by placing them directly into Tunnelblick's folders. (Remove anything you manually placed in Tunnelblick's folders out of the folders first.)
If double-clicking doesn't work, try dragging and dropping them on the Tunnelblick application in /Applications.
Note: Tunnelblick itself must be installed by double-clicking it, **not** by dragging it to the /Applications folder.
The configuration you posted looks OK, but a good connection also requires the server configuration be OK and that the instructions that the server sends to the client (the "push" info) be OK. Often servers push "Windows only" OpenVPN options to the client (your computer), and that can be problematic. See
Read Before You Post for the info to post if there are connection problems.
