After recent maintenance on Confluence, I can't edit an Excel sheet any longer. Ideas?

Before the maintenance task done on Confluence the week before last, I was perfectly able to edit an Excel sheet using Atlasian, very easily too. From then onwards, I'm not able to edit or download this sheet any longer. Support is not answering. Did this happen to anyone else? Did you find a workaround?
