What he want you to do is create a debugging log. Te way you do this is to first find the file. By the file I mean the executable or .exe file that runs the program-in this case the youtube downloader. To start, Applications menu>Wine>Browse C: Drive If you dont immediately see the the folder it will most likely be in the "Program Files" folder. Go into the Youtube Downloader folder and find the .exe file that should be it. The point of this is to find out the location of the file to input into the terminal. The location will most likely be /home/YOUR USERNAME/.wine/drive_c/Program Files/YouTube Downloader What you need is /.wine/drive_c/Program Files/YouTube Downloader You'll need to put parentheses on some of the folder names to make the terminal accept them so this is the end result, plust the command used to open it. cd ~/.wine/drive_c/"Program Files"/"YouTube Downloader" Open a terminal (Applications>Accessories) and paste the above (ctrl v does not work) from here type the wine, the name of the exe file (something like ytdwnldr.exe) followed by &> log.txt wine ytdwnldr.exe &> log.txt Thats how youcreat a debugging log. In the same folder you will now find a txt file named log. Open it and post the contents here.
