export dataset to csv - button missing after one export

Hi,

Having more issues with adobe 8 (man...) we used the export data button to export all our package data to a csv file, now after closing and reopening the file, there is no export data button, and even better, there is no way to export the dataset to csv through the menu's. I've looked for updates in case this is a bug, but no updates are available....

Not as impressed as I was originally with the product, doesn't seem intuitive enough for the audience it is obviously designed for.
