Intervideo discmaster 2 not working

After intalling Intervideo dvd copy 4 i could no longer use discmaster 2. Win Xp Event viewer gives this message:

I have tried installing in different orders but it makes no difference. Dvd copy 4 works fine just not discmaster.
Any help would be appreciated.
Thankyou
