Hi,
I don't know about all these problems, but there you go:
1. Noticed the same thing with an older version of the unity integration, nowadays I don't bother fixing it, I just play it nice and put my banks in the default folder...
4. I had the same problem, and it seems it was related to unescaped spaces in my unity project's path. A friend of mine modified AkWiseIdConverter.cs and it seems to work ok now. The fix is to replace line 43 of the script to :
start.Arguments = string.Format("\"{0}\" \"{1}\"", m_converterScript, bankIdHeaderPath); // escaped spaces
Hope that helps :)
