for anyone finding this....

these steps worked perfectly for many hexalocked CDs containing large pdf manuals.

1. load the disc,in XP disable auto run. Explore the disc & launch the HCPS loader ,likely "hcps.exe". Minimize this window. Open the folder that contains the unlocker,or create a desk top short cut, minimize. Reopen the CD.

2. Rt click a file off the CD, open with Acrobat.

3. Allow Acrobat to load the file.

4 IF the file displays correctly,close Acrobat .Open "unlocker" and click on the "acrobat" file inside.

5. TWO new windows should appear,one is simply a title for part 2.

6. Pick a file to "unlock", select a folder to output. Click the "load file "
button. NOTE the size of the file , WAIT for any disc activity to take place. The file size will be displayed and they should match. If they do not or you get a "0" file size you have issues with your end not the unlocker.

7 . You could get an error message that you need ms winsock (mswinsck.exe) Google it, you'll find downloads and the needed registry tweeks.

8. IF none of the above is an issue, you should see in your new folder a copy of the "unlocked" file. File size must match the original. if not RETRY.
I have had a few that seemed to go smooth, yet yielded a "0" sized file. On retry they worked fine.

9. You should have a second pdf reader, I use Foxit Reader, this will not open scrambled or corrupted pdfs. If you launch acrobat, the hexalocked file could be read, and you may think you got a successful copy. I know that my copy is successful if Foxit opens and displays the file correctly.

10. You may STILL have a password protected pdf, functions in Acrobat can be locked or disabled in the original document, hexalock just passes these on.

I cannot offer anymore help/advise than this.

Goodluck
