With Ledger 6.8, there is a file contained in your data directory called ADSPROF that is used for locating the eztasks (multi-user locking) and the currency files. The file used to be called EZCURFIL.ld4 back when the version was 6.5. In either case, these text files contain locations to the two system files. If you use Accpac as well as Adagio, you will want to enter x:\ASP for both (where x is the drive that Accpac is installed). If you only use Adagio, then enter x:\softrak\system.

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be working fine because the paths contained in it's ADSPROF data file is valid, but the ADSPROF in your live data is no longer valid.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.

The times I have seen the 'Error 1305' have either been due to the EZTASKS file not found in the ADSPROF path, or the EZTASKS path is being locked by another process. The latter case could be because you are using Accpac Plus and do not have any WSM Lanpaks installed (this scenario locks the EZTASKS file to the exclusion of any other process).
