After trying to do some calculations in Raster Calculation QGIS decided to act weird. After trying to fix it, QGIS crashed and some files that were unsaved disappeared. Started up QGIS again and tried to redo the calculations in Raster Calculations and I receive the following message:
Raster calculator: Could not create destination file.
Do I have to uninstall QGIS and then Reinstall to fix this or is there another way?
