[Nigol]

I just uploaded the Fix, it was so Stupid, I don't even know why it worked in the first place.

Sigil usually puts the text file in OEBPS/Text/content0001.xhtml, well I was looking for the filename in the manifest (to know where it is now). But instead of using a "/", I used a \ to separate the path from the filename.

I just hope that I did not break something else, so please let me know.

Update : It has nothing to do with the / (although that fixes it partially). It is only because your original file was in the folder "text" (look at the case), But sigil renamed it to "Text". Those are little things that you just can't think about, and you help me find them.
