I believe the ramdisk is created and game files are copied during this time.
I would ask for help with C6 error (less than 2GB free space on the disk) which I have since last patch. I reduced files to see if it helps - as expected, it did not. In Retail mode game runs without this error.
Any advice on C6 error? Thanks!
I have recently changed to W8 Pro but had no problems with Unleashed until patch so I think it is not an issue.
EDIT: I found a solution myself - edited Unleashed.xml file to increase ramdrive size to have at least 2GB free on launch of TOR. I just leave the problem and solution here.
