I bought the Namariel CE from Playrix (at $5.99), and got stuck at the same place - Davincino's prison cell in Chapter 8. I see the items on the desk but can't zoom in on it. Like most of you, I also skipped through his dialog - and maybe it's why the desk wasn't active.
The game is too delightful to not finish, so I caved and used a punchcard reward on the SE at BFG. I didn't uninstall the CE. I went ahead and installed the SE too - they are located in 2 different folders so no problem there.
I launched the SE to see if it recognized my CE profile - nope. I was prompted to create a new one. That's expected, so no worries.
Right after creating the new profile, I quit the game and went to the saved data folder (My Documents > AppData > Roaming > ShamanGS).
There were 2 folders:
I opened the "NamarielLegends_IronLord_CE" folder and copied the contents there (2 files - myname.xml & app.ini). Then I opened the "NamarielLegends_IronLord" folder and deleted the contents, and pasted the 2 copied files there.
Back to the desktop, I re-launched the SE to check if it now recognized my CE profile. Yes! It did
I pressed Play and I was back in Davincino's prison cell.
Lo and behold -- there is now a magnifying cursor over the desk! I zoomed in and took the items - a valve handle and a brush! Yeah! Then I exited the game.
Back to the Appdata / Roaming folders, and did the reverse. Copied the SE savefiles and pasted it in the CE savefile folder (overwriting the previous ones).
I re-launched the CE and crossed my fingers... and YES! My game is intact, and I have the valve handle and brush in my inventory. No need to start the game over
EDIT: ok it seems you need to do one more thing on the desk in the SE, before moving back to the CE.
