Was obviously messing around where I shouldn't have been and now ALL my Excel docs open blank (no sheet/workbook - only grey).

Excel APPLICATION itself opens just fine and able to work on my documents, so not a train smash.

I've tried re-tracing my steps which extends from:
Template/Start-up file ("Roaming" and "Program Files" locations) create/delete
AddIns (especially VB) enable/disable
Adjusting most of Excel settings in "Options"
Registry Edits; and finally
Uninstall + Re-Install


..and YET I am still sitting with the problem. Been to the dark corners of the internet ... please help.
