XPP Exception Dictionaries


We had recently upgraded to XPP 9.0 and then had to back out to XPP 8.4 as 9.0 does not have Oracle.pm module for Database interaction. However as a result we are unable to see the Exception Dictionaries which we had prior to our upgrade. All the Dictionary related files are intact on our Unix location. But we are not able to see any Dictionary when we open the Dictionary Maintenance tool. 

When I went through the Release Notes for XPP 9.0 - I can see a release fix for XPP-734 (3.2 in TOC) for integrating all the new Proximity hyphenation/dictionary files, but I am not sure if this changes would affect us. 

Could you please advise.
