We've identified an issue, by hardening some checks, we've introduced forking change.
For now the only fix is getting db from bob: http://bob.nem.ninja/
Getting db from bob doesn't help. In this case NIS gets stuck at block 9216
'Loading blocks from db, at block: 9216'
I had the same issue until I cleaned out the old version.
Run: "javaws -viewer" and delete Trace/Log Files and Cached Applications/Applets.
Delete the C:\Users\<username>\nem\nis\data directory.
Unzip nis5.h2.db-11772.tgz and put the nis5.h2 file in the "C:\Users\<username>\nem\nis\data" folder.
Didn't help. Get stuck at block 9216.
What I did was go to search in windows. Type "Java Config".
In the Java control panel click "view". Then delete all the things related to NEM.
Then navigate to the NEM folder and delete the whole thing. C:\Users\user name\nem
Turn off computer and restart. Download the database file. http://bob.nem.ninja/nis5.h2.db-11772.tgz
Also download the stand alone version from http://bob.nem.ninja/ (I had to unzip it and then unzip it a second time)
Then start NIS in the stand alone. Then NCC. Then close them both down. (open the folder called "package". click "runNis" and "runNcc". If you do this correctly some command prompt boxes will pop up and be running code)
After 30 seconds close the NIS and NCC.
New NIS and NCC folders were created. Paste in the database into the NIS folder at C:\Users\user name\nem\nis
Do not put any old wallets in NCC. Just make fresh ones when NCC starts.
Restart NCC and NIS on stand alone.
