Ni No Kuni issues

Well, my PC is not the best but the first Cutscene of Ni No Kuni goes smoothly. The only problem is when it ends the game just freezes in a black screen.
When I try to skip this cutscene, the second one goes finely, but once it ends I get another black screen.

On Catherine, the subtitles are all fucked up and I have no idea what to do too

Specs: 8GB RAM, GTS 450 (yeah, I know) and Intel i7 3770 3.4 Hz

For the Catherine issue, enable the option "strict rendering mode"

No idea about Ni No Kuni. Attach the log file.

On Catherine the subtitles got perfect, thanks! But the game's audio some times gets pretty laggy. Is there anything I can do?

Ni No Kuni's log(I couldn't attatch it )

That's not a log, I redacted the console output.
