This issue seems to come from your username which contains non-ASCII characters (신현탁), causing Grabber to fail to set the file creation date (but it should still be downloaded properly).

I will fix this in the next release.
In the meantime, you could change your save directory to something else if you want to keep the "keep file original creation date" feature.
