Still getting connection problems...
is your NXT blockchain up-to-date?
You need an updated blockchain in order to mint.
Yes it is.
what files did you edit?
I would try...
1.) Close the nxt java file and your "mint.bat" file
2.) Download the latest 1.4.8 NRS located https://nxtforum.org/nrs-releases/nrs-v1-4-8/ if you haven't done so already.
3.) Copy->Paste the files included within the "nxt" folder that is contained within the 1.4.8.zip file you downloaded over the current "nxt" folder you downloaded previously. So it will just replace all the files that may have been corrupted with newly untouched files.
4.) Do a "Replace All" when it asks you to select what to replace.
lmk what happens.
Be sure you don't touch the "nxt-default properties" file. Create a copy of the properties file and edit the files in the copy you just made with the parameters described in the OP.
OR
1.) create a copy of the nxt_db folder that you have in your old nxt folder. (This is the NXT blockchain folder)
2.) Copy that into the newly downloaded NXT 1.4.8 client "nxt" folder
3.) Create a copy of the "nxt-default.properties" file and edit the files in the copy you just made with the parameters described in the OP also rename the copy "nxt.properties".
