Any ideas on why this is happening again?
Have you checked to see how long you have configured your BB to keep messages for? Go to Messages and then choose the Options menu item. Click on General Options and scroll down to the bottom of the list. The last item is labeled "Keep Messages:". What is it set for? You can set it for as little as 15 days and as long as "forever"...
As others have noted, the memory card has no impact on this - it is for storing files only.
