New cards not showing up at all after error messages

I have been using anki trouble free for several weeks, then I got an error message saying something like file has been corrupted. It then said to follow instructions to fix it. The decks seemed to be working fine so I did nothing. However, a few days after that message I noticed that new flashcards I have been making are not showing up when do my reviews. I have done nothing different with these last few cards. I am guessing this is do to the error message? Older cards are showing up fine. The error message has not shown up again. Any help would be appreciated.

I suggest you search for is:new in the browse screen, and sort by the due column to locate your recently added material.
