Use the file link to start the download in the morph mod. You should start the download paused, since you don't want to actually start downloading the file. This can be done in eMule's preferences. Check which .part.met number it was assigned which can be done by right clicking the file -> Show File Details -> Part.met File. Now exit the SF-IOM mod and delete both the .part.met file and .part of the new download. Rename the old .part file (from the broken download) to the number of the new .part file (the one you just deleted) eg. 001.part. Now restart the SF-IOM mod. It will ask if to recover the download and you answer "Yes". A new .part.met file with no gaps will be created.

Saving broken downloads this way has one large advantage. Completing the guide you will now have a back-up of all of your .part.met files stored in the .part.met index, so if one of you downloads are lost again, you will only need to start up the SF-IOM/morph mod and answer "Yes" when it asks if to recover the download. You won't have to do anything else, everything will be done for you. This won't, however, apply to files you start downloading after you switch back to you preferred eMule client, only those you were downloading while using SF-IOM.

Credit goes to SlugFiller and the SF-IOM mod, current mod that has the import feature is the morph mod.
