I don't think anyone is refusing to help. There are hundreds of posts every day on this forum and keeping up with all of them is day task. It happens that posts get burried.
I just looked up your previous questions and although I'm on the forums on a daily basis and try to check out all the new posts, I can't remember seeing yours. That just goes to show that its not about refusal, it just slipped through which is unfortunate.
Your first issue, about the crash. JimH pointed you to the wiki, in particular the FAQ section which has a topic on
Stability. Have you been able to check it out? Either way, you replied after which is turned silent which is a shame. PS. The fact that other programs run without issues is not a garantee that MC will run flawless too. MC should run stable and if it doesn't there is probably an issue with the OS, drivers, hardware or a conflict with other software. Are you are able to reinstall the PC and just install the necessary drivers and MC?
Your second issue, about auto import not working. Have you searched the forums? I can imagine people not replying because the issue comes up regularly.
Here's one but there are more, Use advanced search feature.
Typically these forums offer first class help, both from the community and the developers. I am sorry you're experience has not been as good.
