The problem has been isolated to two columns. When I copy and 'paste value' cells that are formatted as numbers into a column formatted as number in a table (being used in powerpivot) - then refresh the pivot table - the error occurs.
I have a copy that is working but changing cells in these two columns (even typing by hand) results in this error.
I had a HORRIBLE experience with the Microsoft help desk. They were unable to resolve the issue and REFUNDED my money - then transferred the call to the 'professional' line - where the representative told me this was not a professional matter
and he could not help! He told me he was transferring me to the number I had called the night before - and then I was disconnected. Multiple subsequent attempts to reach a supervisor have been fruitless.
Any advice on how to resolve the problem or contact someone within Microsoft that can help - would be appreciated.
