A lot of Duplicate entries

Good Morning all.
 I am running Windows 8.1.
Gmr v0.17.4

  I added a lot of recipes into Gourmet and have a lot of duplicates. I tried to remove
them and it just hangs but I can still work on my computer. Is there a way to delete these
in the program. No SQL experience at all. I tried both options when I imported the file to
GRM.

Now the backup wont make the xml backup file. I have really messed
this up I think

Thanks
Kemp
