Dear Artem,
Thank you for sharing the log message panel content, it is very helpful. This error message was caused by insufficient disk space on your computer. To solve this issue, please free up more disk space.
Alternately if not possible for you to free up more space you can also try to zoom in on canvas to use smaller area. Next alternative is to use lower resolution.
To give you a bit of background:
In GIS is work with large datasets quite common and users need to allocate big amount of disk space for temporary files which are used in data processing.
Again thank you for sharing this issues. We are aware of this and trying to solve it in the next generation of ur-scape import data manager.
Kind wishes
David
