| acruel 13. Dec 2015 | Are you sure the hostname "nicefahrrad.ddns.net" is resolvable? acruel$ ping nicefahrrad.ddns.net ping: cannot resolve nicefahrrad.ddns.net: Unknown host acruel$ |

| givses 15. Dec 2015 | -1 for not linking against framework 4. |
| HoLLy_HaCKeR 19. Dec 2015 | cannot resolve, I assume I just have to fix it and make it appear? (like when an old program's website is down) |
| elmasmalo1 20. Dec 2015 | the host is definitely down (a ping to the host can show proof of this), so there's no way to actually check for serials or decide whether you can crack this or not, other than you can make a patch that will lead to an obvious cracked program but given the fact the host is down, it's obviously uncrackable which is non-sense. Anyways, if the program would be working correctly, the program would send your computer name to the server and then when it's going to check for serial it will send another string as follow: "CheckSerial*yourserialhere", where you see 'yourserialhere', it's the actual serial you're writting into the program, the program then sits on a Listening loop waiting for a response so then the program would then return a string from the server checking whether your serial was correct or wrong, the string will be located in a RichTextBox that is not visible if the text from the RichTextBox is changed (waits for such event), meaning that we got a result from the server then the serial check routine begins, if your serial was correct you would get a string returned from the server as follows: "yourcomputernamehere*rightserial*" where you see 'yourcomputernamehere' is your actual computer name that we sent eariler, at this time the checking routine does other checks also, but skipping that... else if the returned string is: "yourcomputernamehere*wrongserial*" you will get an error message, now the routine check is done and we how to successfully crack the software. |
