WAV-files from ZOOM are opening incorrectly both in Vegas 12, 13. The sound is reproducing fragmentically, channels are mixed, the waveforms are also displayed fragmentically. In Premiere tracks playing normally. How should I solve this problem in SVP 13?

Hmmm... I have the same recorder, never had an issue with sound... and that includes 40-50 track mixing projects in Vegas 12.

Here's the problem I have: your waveform files. There are numerous realtime issues that can prevent Vegas (or any program) from playing audio back glitch-free in realtime. But none of those involve Vegas's processing the audio to build the waveform previews -- that's not a realtime operation, and will succeed even if the driver were too slow for realtime playback. That suggests that whatever's wrong, it's real, at least to Vegas, not an artifact of playback.

A couple of things. Have you tried these in Vegas without any other assets, plug-ins, etc. Start a new project somewhere else, to force Vegas to rebuild its waveform files. Try that from a different disc. Try re-acquiring the audio files from the H4n SD card. If you have the SD card in an SD drive on your PC, maybe try a CHKDSK... I ran into a problem a couple of months ago with a dying SD card. Didn't really expect that to ever happen, but sure enough, it did.

Playback issues can be other things on your system misbehaving, bad audio drivers (particularly MCI drivers, you might want to switch to ASIO and add a large buffer size, just to see what happens).

If you do have it playing back successfully in Premiere, try rendering it out from Premiere to a new file, but otherwise unchanged. If there was some kind of corruption in the file that Vegas can't handle but Premiere can, that ought to fix it.

That's all I got for now.
