I am using SQL Developer 3.1.07 on Windows 7.
Today, all on a sudden it is giving me error while starting SQL Developer.
Please help me how to fix this problem.

The error message is:
<code>

    It appears the SVN plug-in is giving you troubles, normally you should be able to disable it from
    Tools -> Preferences -> Extensions -> Versioning Support
    Assuming you do not need it.


    Since your system is no longer starting you might have to manually remove the related jar file from the installation, this file is usually located in:
    [SQLDev_install_dir]/jdev/extensions
    and it's name is:
    oracle.jdeveloper.subversion.jar
