Looks like it might be a problem with naming... ie, tasks-0.92b.dll might need to be something along the lines of tasks-0.9.dll, or vice versa. Might want to check that the file names already existing in theme.rc (do a quick Ctrl-F on tasks, shortcut, hotkey, respectively) and see that the names in there match the actual file names of the *.dlls you have installed. If they're different, you probably want to rename the files, since there is a possibility the filename is referenced somewhere else, and you don't want to track down that entry in all the config files
