I'm so sorry to hear Limey didn't make it. Also sorry I didn't get back to you sooner. It seems like there may have been an unseen problem with him which gave him no appetite. Your care was very good and I feel it may have happened despite all your effort. The initial stress could have made him sick or he could have come with it, it's always difficult to say in these situations. My friend's baby pacman didn't eat for nearly a month when she first got him and now he is thriving, so you never know what can happen. Only advice I can offer is to reconsider buying another Pacman from the same breeder and look around for reviews before buying from a certain source.
I wouldn't take it to heart about people not commenting. This forum is not as active as it once was, never seems to be more than 5 members on at a time. And the members who do come on, not all of them own or have a knowledge of certain frogs, so they wouldn't be helpful in advising about them. You can also visit these forums without a membership which is actually how I started out; you can look all you want but you can't comment (part of the reason I registered), so I have a feeling your thread simply had many silent spectators. Part of it could be your thread wasn't in the general Pacman area, too...so there's a lot of factors going into why only Misschic13 and I commented.
Another reason I joined and started responding to many threads was to encourage more discussion and to try and get this place more active again. I hope you aren't too discouraged, it was good of you to catalogue your journey with Limey and it may help many more people who only lurk on the forums for information.
