Are you able to test with a different internet connection ?
If not grab www.pingplotter.com and set it to say www.google.com while the download is occurring and graph when downloading, that graph can be saved as a jpg and inserted into a post here.
well..
The only other thing i can think of for the log to register bad data ,as if it was a CDN more then one person would have this issue currently
Although you can change the dns it should change the CDN used in most cases, like try 8.8.8.8 (googles) as a DNS server for example
Now other causes of that error in the log is usually down to bad ram , this may also explain why both patch methods are failing, SSN is actually way more sensitive to bad memory then bitraider.
other then that cant hurt to do a chkdsk to ensure there are not bad sectors on the drive if not already.
Now another thing with Bitraider is that 5400RPM drives struggle with its patch method and given you have a WD blue drive it is 5400RPM, they actually recommend do not attempt to play once minimum download is reached and wait for the entire game to install - see streaming in this link
System:
If your system has any of the following, we recommend you wait for the download to complete before playing:
Hope this helps
