PPSSPP and Daemon Tools behaviour

[Gurlok]

For some reasons, whenever I mount and then unmount any image file (to put it simply, when I use the daemon tools basic features) and then I decide to use the PPSSPP I get a warning message, in which the emu says that it can't find anything in the virtual drive. I can't reproduce always this issue though. I'm sorry for being unable of expressing myself better, but I don't know how to put it in a more simple way .
