I just do the refund. ;)
The only solution was to have decrypt all files in order to regenerate a name for these functions, except that by this kind of solution is likely to have errors corrected by hand.
This is the challenge that I give for version 2 that I developed now to provide a more complete decryption.
well the complete project is pretty large (maybe 200 files)
and i managed to decrypt most of the files with free tools myself...only this file and around 20 other files are giving me hard times.
i can also send you copies of the files i managed to decode...and older, non decoded versions of the project...maybe that helps.
maybe we can settle on a good price, for example similar to your 25 files version.
