Photo-Paint X3 not working


I'm new to this forum so forgive me if this has already been asked (not had chance to lok around yet). I have Photo-Paint X£ as part of DRAWings X3 which includes Corel Graphics Suite X3 and Drawstitch* (*an embroidery digtising software program). I have been using Photo-Paint alot with otherdesign software and it has recently been working very intermittently - sometimes it loads and at others it won't. I have un-installed the Graphocs sute and re-installed it and re-booted my laptop several times (I run Windows 8.1). I know it's an old program now but it does the things I need it to so I'm reluctant to get something else. Can anyone suggest what to do to permanently fox this prpblem please? Any help would be greatfully receive. Thanks
