Blue Iris UI3 not working

[BadBlake]

Try opening the path C:\Program Files\Blue Iris 4\www and see what is there.

It seems most of the files are missing from your www folder, hence the 404 errors. No idea why they would be missing. To fix it, you can re-install your last Blue Iris 4 update if you have the file available still, otherwise download UI3-77 from here and extract it into the www folder. When finished, you should find login.htm and ui3.htm in www, among some other files. If they disappear again, check your virus scanner exclusions as it may be quarantining the files for some reason.
