Not sure if this is your problem but will mention it just in case. When you close GD by pressing 'X' in the upper right corner, it does not exit the program, it only puts it in the tray (it can be among "hidden icons" in the lower right corner of the Windows). If you try to start another GD, it won't do it because GD is already an active process. You should go to the tray and press on its icon there.
To actually exit GD, you need to press Ctrl+Q or go to the menu "File" and then select "Quit" at the bottom. However, as Gloggy mentioned, you don't need to exit and restart GD to update dictionaries. Just press Ctrl+F5 after you change the dictionary file.
