I unexpectedly got the following error message: Note Item not found
I was worried that the problem was about having both R8.0.1 and R8.5 beta Notes clients on the same pc; after uninstalling R8.5, I reinstalled client Notes R8.0.1 . No way!
Before getting crazy, I luckily found an IBM technote to solve that issue:
Error: 'Note item not found' when creating new database using Blank template
Reference #: 1307244
Modifying the Notes.INI?
You know what? I decided to create a blank template db on local, then I replicated it on the R8 server ;-)
