Hello tt2
I wanted to let you know, that I did turn off the computer last night. When I logged back in today, I was able to open iTunes again. So that is no longer a problem. I was just writing a description to start a new discussion, (I couldn't find a place in your last message to reply, hence the new discussion) but I rechecked your answer again and saw I could reply, so I thought it would be more efficient and not as rude if I brought the problem back to you. So, here is what I had written :
I am using a desktop PC that was recently (> 30 days ago) completely checked out and the Windows-10 upgrade that was causing so many problems was removed and Windows-7 installed again. I have double checked that I have the latest version of iTunes installed. One thing that is different since I had W-7 installed again, is that everytime I go to open iTunes, I get a popup asking if I want to let Apple make changes to my PC. Other than being a minor irritation, I have not had a problem with it. The problem I am seeing now, is everytime I try to buy a song from the store, I get an error message that says "Your request cannot be processed. Error code: 5105". This just started in the past 24 hours. I have ensured my credit card information is correct and updated. I rechecked my whole account, and found no errors.
The other things I have done recently, but several days before I started getting this error code is a) shared music between my iTunes library and my Amazon library, b) shared a playlist with my Windows Media Player, and c) installed the trial version of Nero Platinum 2016 before I purchase it, and the Nero Media Home automatically collects information from all files I allowed, which was all photo files and all music files. Those are all of the outside sources I can think of that may possibly influence my iTunes account. Although I have no idea why any of these things would prevent me buying songs from iTunes.
I wanted to apologize for the tone of my question to you last night. It was certainly not your fault I jumped into a problem "fix" I just assumed would work for me. So now, I am asking for help with my error code 5105. I need to know if I Should start a completely new discussion after all. Or if you would like to pursue this under the current thread.
I do thank you for your support, and again apologize for my rude tone earlier. I will await your response before I submit a new discussion.
