Neoload 6.8. write a scenario

I've just started to learn Neoload and I bumped with then next problem:

I have simple local site on virtual machine and I try to record simple scenario with a few actions (home page, login, logout). I tried Neoload 6.7 and 6.8 versions. When I used 6.7 everything is fine. When I used 6.8 version it doesn't recorded any actions on my local site. It works only with public resources (If I run VM with my test site in public cloud everything is fine). I used default preferences for both 6.7 and 6.8 installations and din't use proxy. Probably I need additional configuration but I didn't find any tips in documentation.

Thanks in advance.
