The error below was reported in the .log workspace file.  

!ENTRY org.eclipse.core.net 4 0 2013-09-26 10:50:41.813
!MESSAGE Unable to locate secure storage module (org.eclipse.equinox.security.windowspasswordprovider).
!STACK 0
org.eclipse.equinox.security.storage.StorageException: Unable to locate secure storage module (org.eclipse.equinox.security.windowspasswordprovider).
    at org.eclipse.equinox.internal.security.storage.PasswordProviderSelector.findStorageModule(PasswordProviderSelector.java:190)
    at org.eclipse.equinox.internal.security.storage.SecurePreferencesRoot.getModulePassword(SecurePreferencesRoot.java:231)

Cause:
============
Eclipse uses a default location on your machine which is the same for all your Eclipse installs. If you have installed and used 32-bit Eclipse, then your secure storage requires the 32-bit plugins to access. When you try to use a 64-bit Eclipse it will try to read that secure storage and will fail because it is using the 64-bit plugins to read the storage.

The second link provides the reason on why this could be happening.  The solution is to tell your Eclipse to use a different secure storage area. You can do this by running Eclipse with the following option:

-eclipse.keyring &ltfile_path>

where &ltfile_path> is the location of the file which you wish to use as your new secure storage area.
