Updating my protected file ?

NETGuard will make you pay one token for each time the file is different from the last sent file.

That means, if you want to obfuscate YourProgram.exe v1.0 it will costs you one token. If you want to obfuscate it again right after, since last sent file is equal to YourProgram.exe v1.0 then it will not costs you a token.

However, if 2 hours ago you protected YourProgram.exe v1.0 and now you want to protect YourProgram.exe v2.0 then it will costs you a token because the file is a new file.

We use MD5 comparison to determine if files are equal or not.
