Something that had bugged me a little bit was that Trial sticker every time I start KidCoaster. Even though the new package was supposed to be a fixed version of KidCoaster, I guess the developers didn't bother to think clearly and packaged the trial version. I kept a copy of the old KidCoaster package and did a MD5 check, and here are the results:
F3B8A556375F60F7A230FD8EF88EFC95 KidCoaster.exe (the one from the original/broken package)
73571A0A487B511E79142AD8A23D6EB9 KidCoaster.exe (the one from the new fixed package)
73571A0A487B511E79142AD8A23D6EB9 KidCoaster.exe (the one from the trial package I downloaded from KidCoaster's website)
I'm fairly sure that the first package posted on GOTD is registered while the second one was not, hence the difference in checksum. (Also hence why there isn't a Trial sticker on the first one.)
I think the GOTD team should get this fixed. I am not sure how the trial works (is it a registration code or a completely different build?). But in any way, KidCoaster should be rerun.
