Welcome to the OptoForums! For this kind of question, I'd encourage you to take advantage of our FREE product support [click here].
However, I noticed you mentioned PAC Basic 9.0. Our current version is 9.3, which you can download for FREE here.
Is there a particular reason you wanted that older version of PAC Project? If so, did you get the newest/best 9.0 archive (9.0006), from this location:
(the opto22 ftp site)?
If so, then your best bet would be to contact support: firstname.lastname@example.org.
Hope that helps!
