Talend Studio Error for org.eclipse.ui.workbench

[mdaly]

My TS projects were working okay this morning. This afternoon I am getting the following error: "An error has occurred. See error log for more details. org/talend/repository/services/model/services/ServiceItem". After some internet searching, nothing obvious for a resolution. Help? 

Error log:
