Every time I bring up the ddo software, a screen temporarily comes up that says, "Installing prerequisite software". Then, when the launcher is checking for updates, it always shows me as "Installing files 1/0". This almost immediately disappears, then ddo runs just fine. However, if I keep playing it long enough, it will crash w/o warning, and I get a windows error message telling me the ddo client has stopped working. Once I get rid of that message, I can immediately restart ddo and play again with no problems-right up until the time I crash again.
