Problem Saving New Products and/or editing old!

Hi I can't edit or save new products! It just says: "Error - Save failed" (or in Swedish: "Fel - spara misslyckades")

It's a new website and the first products were imported by CSV-file. Have anyone had this problem before?

This is the error message I got!

It didnt work Im afraid! Do I need to uninstall it completely to make it work? Could it be that its something caused by the CSV-file that was imported? So if I reinstall it and run the CSV-file again i'll get the same problem again!?
