Thanks for the report. The crash happens not when loading one of these styles, but when auditioning (either by double-clicking or via the green play button in the StylePicker) a style with a % symbol in the filename that does not have an audition file on the local disk. Since there are no audition files on the disk, it wants to search online, and gets stuck on the percent symbol.

StylePicker --> Actions --> Dialog Options --> uncheck "Use Internet". This will prevent the crash from happening. Alternatively, you could have audition files on disk. They are .m4a files with the same name as the .sty. These get saved in RealTracks/Data/Style Demos Audio.
