Excel Errors (V8.4.1)

Hi,

A user is facing two issues with Excel add-in.  XFGetCell and XFSetCell formulas with XFGetMemmber Property are used (XFGetMember function only at the top of the page). There are 15 sheets in the Workbook page.

Has anyone experienced issues described below?  What is the likely solution?  Is it V8.4.1 specific issue? Thanks in advance for any help/pointers.

Two issues:

(1) Retrieval formula dont work and have to keep refreshing the whole workbook/worksheet. When refresh one worksheet, the rest will went error. When refresh another sheet, previous sheet went error.

(2) When trying to save an offline version of retrieval file but error keeps pop up as attached.
