Ok, thank you for checking your Eclipse version number, additionally please navigate to your workspace directory and find your .metadata\.log file, open it up and look near the bottom of it for exceptions related to the wizard failing (you can keep the file open, make the wizard fail and then find the new exception in the file) and paste it here for me to look at.
Also, click on Help > About > Configuration Details, and copy-paste the 1st 2 pages of information here for me to look at as well.
