I have been trying to install the latest Eclipse IDE for Force.com, but kept running into the "Invalid Api version specified on URL error". It's similar to this thread
Force.com IDE unwilling to create New Project
But I can't for the life of me figure out why it won't connect to my account when I try to create a new project. It just keeps on saying "unable to fetch Organization detail"
I'm using a developer account that was created 2~3 weeks ago. I was following the install directions through here
https://developer.salesforce.com/page/Force.com_IDE_Installation
- Eclipse installed – Version: Kepler Service Release 2
Build id: 20140224-0627 - Java installed – ver 7 update 60 (I have ver 8 update 5 installed prior to trying 7/60)
I have also tried to create the Project offline then create classes that way, but get the same error. clicking work online produces the same error… I'm not sure what else to try now.
Side note, I've only used Eclipse when I was in school (3~6 month I think) and that was 10 years ago, so please be patient with me. (I read a couple threads and noticed a bunch of guides that sent my head spinning, unsure what they were referring to most of the time…)

Uncheck 'Show only the latest versions of available software' and install version 30 of the plugin.
adnsandbox.com is mentioned in the help documentation but I would much rather use the standard installation source.
You may need to uninstall version 31 by going to Help > About > Installation Details.
Once your org has been updated to version 31 you can uninstall update your plugin to version 31.
