One of the team mate not able to access anything in VSTS even with exact same permissions as others

Hi there,
     I'm not sure why this is happening as most of the people are able to access Project just fine and open bug, query bugs etc. just fine, but one of the team mate with exact same right and permisions as other is not able to open bug, see query or even reports are not list in Under Reports section. in Team explorer for her. When she get to the part about trying to add a bug, it does not do anything.  She is  also unable to run any of the project queries.but when she clicks on Active Bugs (or any other item) it does not do anything.  When she clicks on the same item the second time she  gets the following error dialog “Document not found: vstfs:http//seabug01:8080/Cuttituck/Results/Existing/954bc6de-d4fe-4e49-b7c8-1206ba024a56"

When I go and check Server it has following error in the eventlog , which is related to her...
