 See above, Excel documents are not possible to edit

I havet bought downloaded Office suite pro and the programme works as expected with Word documents bur not with Excel documents. It is possible to create new Excel documents but when I open already created Excel documents they are not possible to edit. In thé upper left corner there is a button labelled "Redigera" (edit) byt when pressing that button thée page four buying and download thé programme appears.
