in case anybody else experiences this problem:
i've just found out that i'm getting these uimbus/uim_im (universal image mounter) errors too.
so i downloaded revo unistaller, but of course there aren't any paragon entries there, as i uninstalled it a while back while testing.
i didn't feel like installing paragon again, then force uninstalling it, so i did some snooping around and found three files in windows/system32/drivers:
then i cranked up regedit, searched for uim, found some entries in HKLM\system\controlset\services (and HKLM\system\controlset001\services) and deleted them.
crossed my fingers, rebooted, and problem solved
