Strange, Strange Problem when playing Ponzi games

[ThyDude]

Okay.

I just got coins to play a few ponzi games.

I sent off my coins in to a few games, and a few have paid out already.

Now, a couple of them I made multiple deposits to.

When I noticed the address I was using, it was different than a previous one. Confused, I started to look at my receiving addresses on the coins I already got.

Well, it was 1QATc4ixXTL9EGAW3jey47f3k7fstDTZY3.

Now, looking my bitcoin client, I DONT EVEN HAVE THAT ADDRESS.

And to top it all off, I'm missing my payments back on my ponzi games.

Why could my client have just got rid of an address?

I'm so confused.

If anyone can help me on AIM or something that'd be great.

Please let me know.

After an address is 'used' it cycles out..attempting to preserve anonymity.
The address is of course still legal, it just doesnt show up on the main bar area of the client.

-Are you sure you used the correct address for these games?
-Have you checked www.blockexplorer.com to see if the payouts were 'actually' made?
-Nothing shows up as received in your bitcoin client?
