Just had a look in the d/b Jim
AE1FAE is in as 10-72159
4B198F is HB-JRR and has been in the d/b as such since 14/12/2010
Checked my d/b explorer and AE1FAE isnt in as I would expect as I only entered it in the d/b this morning. HB-JRR is in database explorer as above.
You must have a corrupted d/b Jim
