I am running SpringSource Tool Suite

Version: 2.3.2.RELEASE
Build Id: 201003230009

on Snow Leopard... When I try to update my IDE by going to Help -> Check for Updates, a dialog box appears stating:

"The software items you selected may not be valid with your current installation.
Do you want to open the wizard anyway to review the selections?"

After clicking on Yes, I get the following Dialog box:

"Available Updates
The operation cannot be completed see details.

Cannot complete the install because one or more required items could not be found.
Software being installed: SpringSource Tool Suite Grails Support 2.5.1.201011111000-RELEASE (com.springsource.sts.grails.feature.group 2.5.1.201011111000-RELEASE)
Missing requirement: SpringSource Tool Suite (required) 2.5.1.201011111000-RELEASE (com.springsource.sts.feature.group 2.5.1.201011111000-RELEASE) requires 'org.eclipse.mylyn_feature.feature.group [3.4.0.v20100601,4.0.0)' but it could not be found
Cannot satisfy dependency:
From: SpringSource Tool Suite Grails Support 2.5.1.201011111000-RELEASE (com.springsource.sts.grails.feature.group 2.5.1.201011111000-RELEASE)
To: com.springsource.sts.feature.group [2.5.1,2.6.0)"

This is somewhat ood because I do have Grails support installed...

Does anyone know how to alleviate / resolve this issue?

Kindest regards and thanks for taking the time to read this.
