A Problem in VobBlanker - "error: cell not found"

[iting5]

I used one of the guides here to add hebrew subtitles in hebrew to a DVD movie... after i add the subtitles i need to replace the main movie PGC with the edited one and reauthor the movie, both with VobBlanker.
But when i try to open the VIDEO_TS.IFO of the original movie so i can replace the PGC i get an "error: cell not found" on the 83% mark.
anyone familier with this problem and think he can help me?
Thank you all... any help would be welcome.

*Think* VobBlanker replaces the titleset cell by cell, & might note an error when the count doesn't match. But this is a guess -- don't remember the exact way the warning was worded the one time I had a problem. If I remember correctly VobBlanker starts out listing cells in original & then in replacement & number should match.
