HALIONE not showing all soundbanks

ive updated to Cubase 7.5 and now halione wont show all my soundbanks …im only getting to choose 46 sounds instead of the hundreds I should be able to choose.
ive reinstalled Cubase 4 and updated it but it still wont display in Cubase 7.5 .
I have written lots of old songs which uses halione banks and now they wont load into Cubase 7.5 because it cant find the missing sounds.
ive tried locate contents and I can find the folder correctly and its displaying them but it wont load them…
I hope someone can help me…many thanks
