Error 3253 when downloading anything
Starting a few weeks ago, anytime I download anything in iTunes for Windows (I mainly download apps), a large percentage of them fail with a 3253 error. I can keep clicking retry and eventually they will download. I've also found that if I disable "allow simultaneous downloads", that I don't get the errors so the problem appears to be an issue with downloading multiple things at once. I never used to have a problem with that, it just started up about 2 to 3 weeks ago.
I don't have any issues downloading apps to my iPad or iPhone, only on my PC.
I haven't made any changes to my system or router or anything. Anyone have any idea how to fix this?
