When I log in I'm getting a popup box that asks if I want to download to my hard drive, even though I've already told it to. When this was happening way back, I found it was because CCleaner was removing the file. I put an exception in CCleaner, and the problem went away. I'm wondering if the file name has changed recently. The exception is still in my CCleaner as \XPJAUBJK\bushwhackers3.djartsgames.ca\*.*

If you right clicked on BW while loading and moved that slider that could change things too.
But perhaps a corruption in your computer made that change for you.

What happens when you 'allow' flash to store to your hard drive?

You MUST be sure that the checkbox is unchecked in that flash option of you will get that question every time you load the game.
