Here are some suggestions:

thanks for your reply.
I try.

Please use the most recent nightly build, 4.6.2 is 10 months old at this point. If the problem persists, then please send us the log file.

thanks a lot.
I tried to use nightly build 4.7, but couldn`t import DICOM data in tha same way.
I attach the log files.


Thanks fore reporting. Instead of sending a screenshot, could you please attach the log (as text, from menu: Help / Report a bug; log is available for the last 10 sessions, not just the current)? Before submitting, have a look at the text and scrub any patient information, if there is any.

DICOM files path may be too long. Choose a shorter one, for example C:\SlicerDB. Also, shorten path of DICOM files before importing them, using DICOM Patcher module.

thanks a lot.
As you say, using DICOM patcher, I could import my DICOM data.
I will contact you if I need additional information.

This fixed the same issue for me - it seems that the slice names were too long.
