Unfortunately such a question would probably be not a good fit on any Stack Exchange site.
We prefer specific questions and this type of support questions cannot be answered within the boundaries of the Stack Exchange system. It would require back-and-forth discussion/communication between you and the answerers ("Does X help?", "Have you tried Y?").
This type of question is better asked in forums and not on Q&A sites.
What you could try is to ask for a certain work step ("I did X and try to do Y now but I have this problem: ...").
As @fbueckert said you could try Arqade. After scanning the site list I can find no other site that seems appropriate though. If you find one, be sure to read their help center /on-topic page to make sure your question is truly on-topic. Also consider taking the tour on the target site.
