Excel 2010 Powerpivot workbook constanly crashing when editting pivot tables

Question

I have a quite large powerpivot work book that I store on dropbox.   If I want to add the same field twice I go tot  the normal pivot table field list and drop the field into the pivot table again.  This used to be fine.  I could
then make it show the difference form previous period or similar.   Recently after doing a couple of these or changing the number format excel just crashes.   I have tried rewinding my workbook version back to older versions and still the
same issue.  
I tried just taking a simple single sheet of data and creating a new powerpivot model. i then dropped a couple of measures on to the pivot table and then the same measures again form the regular pivot table field list. I then tried to change on of these
to show values as % column total and crashed. so the problem is excel not my workbook.
I have run the repair through control panel and run sfc /scannow but problem persists. In event viewer the error shows as

Hi,
We can find the dump file after Excel crashed again. Please see the following steps:
First enable app crash dump collection by copying following words into notepad, saving it as dump.reg and importing
it:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\localdumps\EXCEL.EXE]
"DumpFolder"=hex(2):63,00,3a,00,5c,00,63,00,72,00,61,00,73,00,68,00,64,00,75,\
  00,6d,00,70,00,73,00,00,00
"DumpCount"=dword:00000010
"DumpType"=dword:00000001
"CustomDumpFlags"=dword:00000000
Then, open Excel
to repro the issue. If crash issue appeared, please find the crashdump file under c:\.
To further help you, please upload this file into Skydrive and shared the link here.
Also, you can try to analyze dump by yourself if you would like to：
