- make sure the db is in the same file structure (nxt-default.properties will tell you)
- make sure properties points to the file (again)
I've never tried this service or on windows, but I've heard this works somehow.
But it sounds like you might be using the installer version of Nxt rather than NRS?
Thanks for the responses. It turns out I was running the wrong version!! I was running the installer version when I should have been using the NRS. I just downloaded the NRS and it seems to be working now and the blockchain file I downloaded is now recognized although strangely, 1.4.16 didn't work once the lib folder was deleted so I kept it. The NRS doesn't slow down my computer as much as the installer version too which is good to see although I'm not sure why this is the case.
EDIT: I decided to switch to version 1.4.15 of the NRS instead but everything else is still the same.
You were too quick, installer now updated:
