My own flashcards are no longer showing up

I'm using lingvosoft flashcards:

LingvoSoft FlashCards 2008 English<->Japanese Kanji Romaji for Pocket PC
Version 3.7.50
Product ID: FC-PKPC-ENJAKJRM-NT-3750
Build: 10150

with flashcard builder:

LingvoSoft FlashCards Builder 2008 for Windows
Version 2.1.25
Product ID: FB-WIND-NT-2125
Build: 10128

Anyways, I have several hundred flashcards that I had put in myself; the flashcard database is still there, it is the same size it was before my flashcards disappeared. However, the words I have put in there are no longer coming up in my dictionary. It says dictionary is empty, but the dictionary is associated with the file full of flashcards. I'm very worried. So I hope this is recoverable.

I've waited more than a month and I still haven't received a reply to this. I have my flashcard files. They are still intact. There's al ot of flashcards in them.. several hundred, I believe more than 500. Anyways, They are not opening! it says the dictionaries are empty! I copied the .fcu files to my desktop, and I can read the definitions of the words when I open it in notepad. But lingvosoft flashcards is not opening them. Any help with this would be greatly appreciated. Thanks.
