Let's see now. Trouble adopting, which is related to kids, family additions, etc. Could the problem be (ominous music) THE KITTEN KILLER?
Not a sure thing, but you might test this. Wouldn't be the first time that Inteen caused unforeseen problems.
To be fair about 99.9% of all problems with the kitten killer are either user error or the program working as intended and advertised by it's own documentation. An example of the former would be a hack conflict (the biggest culprit for inteen related problems). An example of the second would be "ZOMg my sim just had a miscarriage!" which would be one of the program's normal functions (if your sim has certain low motives then it is randomly determined if she will miscarry. A flavorpack is available for nomiscarriage for those who prefer less risk).
The point is that some of us carefully manage and organize our downloads folders. Some of us carefully read documentation. Some of us are not total fucking morons, and we realize that such a large and invasive hack must be handled in a certain way. For example, before you go around asking for help you should first remove said program and see if your problem persists. If it doesn't then you should reread the documentation to make sure that it is, in fact, a bug (not a feature), to see if it is a known bug with a specific workaround, and to see if you have a hack specifically known to make the game go wonky. If you've done this then you should submit a bug report to Jase (not MATY, duh). If this sounds like too much work then one shouldn't use the mod at all. If the OP has done this stuff and is certain that the kitten killer is not the culprit then she probably should have mentioned it. If she hasn't then she behaved foolishly.
That said, I have never had a problem that I could trace back to the kitten killer. If I did find that it was causing a problem in my game I'd report it to Jase, not here. I am not the most polite person in the world, but I know better than to ask MATY members to solve/diagnose a problem with someone else's work. Of course, I also think that it is important for me to do most of the detective work myself before reporting problems (I've saved myself from humiliation once or twice thanks to searching here for keywords related to errors I've experienced). That is probably because I'm not an idiot.
My point? I'm sorry, but I'm just sick of being lumped in with the morons who don't know how to manage their hacks properly. And maybe some of us like being of questionable moral fiber and simulating the horrors of consensual sex between teenagers (and perhaps the larger issue of expecting them to cope with the consequences of said act. That's the really offensive part, right?) but that doesn't mean that we are ALL stupid (although the majority of humanity in general is probably stupid, so it would be fair to say that most kitten killer users are probably stupid and probably don't follow these steps).
Ok, I think I'm done ranting now. Uh, sorry about this, but it has been bugging me for awhile.
