All Americas units come with 30W-139W pre-installed and saved as default. Upgrade instructions with each firmware release have instructions to make a backup and to use the correct mode so you don't overwrite the database. Since all the release software are "patches" they don't contain NA satellites. Just take your backup and use it in "channel list" mode to put your satellites/settings back in.
User_Error means exactly that....you did not do the upgrade correctly. This is why each software has detailed step by step instructions in the ZIP file starting with making a backup in case you do something wrong. The STB's even have a big white slip on top of them about making a backup and the link to step by step videos guides for the STB here: http://www.namini.tk/index_files/Page335.htm
Satellite database is limited to 64 (62+reserved DVB-T/C) and since we send NA units with the satellite db full there is no "add" option.
What you probably should do is contact your dealer for assistance in getting it back to they way it was. There isn't much I can do to assist you with it if you skipped the step concerning making a backup.
