Innerspace Crashing

In the last two weeks, Innerspace (build 5326) has been crashing on me quite frequently. I am playing the game Runes of Magic and 6 boxing. It is less often that Innerspace crashes while I'm fully loaded in game with all 6 characters but more frequently that it crashes while first loading my 6 accounts. Innerspace might load 2 of my accounts, and then freeze, not opening another instance of the game. Even when I try to right click the Innerspace icon in the tray, nothing happens. So I am forced to shut the program down in Task Manager. When I do this, and reload Innerspace, the rest of the instances usually will load. However, sometimes, Innerspace will reload character 2, for example, when character 2 is already loaded.

Does anyone know the solution to this problem?

The character set I play most often, which is the one I'm having problems with, is called Rom MB. Thanks in advance.
