Have you tried restarting your computer? After extensive cleaning your computer may need restarted.
Otherwise you may need to restore to a point before the cleaning and then use a cleaning tool such as CCleaner (free) or another cleaning program you pay for to clean only those files that are useless.
You can find good cleaning programs on Cnet or File Hippo websites.
This may not fix your problem, but if a file was deleted that you needed and you can't restore it you may need to download something again.
I've been getting "error code 8352" where the player just stops and says to close the browser and restart it. If it persists to call Customer Service. This has been happening a lot lately. They've also told me to contact Microsoft.
They did suggest this as a temporary solution:
Click on "Your Account & Help" [located at the top right of all netflix pages] scroll down and click on "Manage Netflix ready devices and computers" then click on "Deactivate" by all the ones listed. They also said that it may take up to 24 hours to allow access, but in the times that I've deactivated, it only happened once that I wasn't able to deactivate. I haven't found a proper solution for this either.

"4. Whispering Corridors 2: Memento Mori (Kim, 1999). Atmospheric girl school ghost drama. It made even less sense to me than the first one, mostly because I couldn't keep track of who was who and when (no offense, but Korean school girls…"
"3. Spasmo (Lenzi, 1974). A giallo? that features none of the staples (requirements?) of the genre? Apparently. A psycho-mystery-triller involving faked murders and a lot of people acting completely irrational. No blood and gore, no crazed killer…"
"Yeah, it's in the 2-3 star range. As a horror movie it sucks, but it has some things going on as an art house movie. Czech New Wave is (or at least can be) very weird. It's like their brains overdosed on the sudden brief freedom."
"2. The Cremator (Herz, 1969). Czechoslovakian art house horror. Or at least art house. I'm not sure why it's labelled horror, it's more of an unsettling drama. Set in Czechoslovakia in the late thirties, shortly before the German…"
