Importing of survival shooter tutorial ends in an endless loop

Hi,

I’m trying to import the assets from the asset store for the survival shooter tutorial. Unfortunatelly the import of the fbx files ends in an endless loop.

Tried it several times, but always it hangs up. No error message no crash report. I let it also run for at least half an hour with no progress. The task manager said that there is no cpu usage in the unity editor, so it doesnt looks like that unity is computing very much.

Hopefully someone can help me.

Thanks

Added a thread in the forum, hopefully someone can help:
