Okay, it could be that there are one or more files that are corrupt.

You should do a DIC, make sure you have a current backup and if there are errors and the Rebuild button presents itself, Rebuild the data and rerun the DIC.

However, it could also be that you will have to look through your data and (making sure that no one is in Adagio at the time) selectively rename a file and then try to reopen the financial reporter.

Examples of files you can look at are GLATREE.xxx or GLDTREE.xxx or GLACCGRP.xxx (where 'xxx' is your 3-character data extension). I would not suggest deleting these files but renaming one of them (eg. GLATREE.xxx to GLATREE.old) then reopening GL and trying to access the financial reporter. And, moving on from there.

This may be something you want to contact your Adagio dealer to help you out with.
