This developed into crashing whenever I opened the options menu after startup to enter my PXO information, which then turned out to be an out-of-bounds error with some slider; I deleted my .plr file, which fixed that. Now it crashes when I try to connect to PXO; debug logs and cross-checking with the code reveals this to be because the code that loads the PXO background bitmap is erroring out due to not being able to find it. Indeed, I do not have the file it's trying to access; but it worked fine before, displaying a black screen, so I don't know why it changed.
