From my (and Warren's) post:

Sample data may be working fine because the paths contained in it's ADSPROF data file is valid, but the ADSPROF in your live data is no longer valid. You have two options:

- Copy the ADSPROF from your sample data directory and paste it to the directory that contains your live data (overwriting the existing file).
- Delete the ADSPROF file in your live data. The next time you start any Adagio program it will be recreated. A prompt will ask you to enter location of the eztasks/currency files.

So - it is the ADSPROF.xxx (where xxx is your data selector) that needs to be reset (not EZCURFIL). You must have changed the drive letters or directory layout on your new computer.

As a note, there is no need to install each of the Ledger version in turn. When faced with this situation, you can just install from the most recent release.
