HsGetValue function not refreshing

Summary:

Workbook with HsGetValue functions not refreshing for a single user

Content (required):

Workbook with multiple HsGetValue formulas on it. Works fine for multiple users but for a specific user it does refresh. When she uninstalls SV and reinstalls, it works (returns correct database values) once or twice, then stops. Hitting refresh button seem to do nothing. Cells show #NAME, as if it does not recognize the formula any longer. SV add-in is not disabled. Excel version MS Office 365 desktop install. User can create ad hoc against same cube and refresh fine. But HsGetValue report nothing. Anyone seen this sort of issue?
