The problem appears to be that Excel is trying to open your csv file on line rather than allowing you to save it to your HD and then open it. That worries me a bit because that is the sort of action that could be initiated by a malformed macro. I would suggest that you change the way in which csv files are handled. If you go to Start, Control Panel, Folder Options and click on File Types you can either change the programme that opens csv files or change the way in which they are handled. You can, for example, change the option to Save rather than Open. I would probably just tell it that you wish to use Notepad to open csv files and see what happens.
