Unable to upload files in Vista(32)with correct file names

I have been unable to upload .csv or .jpg or .jpeg files to another website in Vista (32).

When I browse for the files, I get an error message which says that it is an incorrect file name. I know that the file names are accurate, but browsing will not locate them.

Also, the only way I am able to find the files (they are on my C drive)is to click the Start and enter them at the bottom left. They appear in the Start area on the left of the screen.

I have uninstalled and reinstalled Vista recently because of other problems, and I have a registry cleaner.

Help! Help! Help! This is a major problem for me!!!

Hello, For one, stop using any Registry cleaner programs, you have probably done more harm than you realize. Go to a restore point before this issue . See this : http://www.vistax64.com/tutorials/76905-system-restore-how.html

Re: System Restore - How to

I am not very computer savvy due to health issues. I do not know when my file uploading issue began, and I only noticed it about 3-4 weeks ago, because I needed to upload a .jpg or .jpeg file for a new business I am setting up.
Therefore, I do not know what Restore Point date to use. It will probably be trial and error. About 6-8 weeks ago or less, I had to reinstall Vista, because it was badly corrupted by a virus, trojan, or worm. So, the file upload issue may have existed for some time. Prior to the reinstall of Vista, I tried Restore points to try to fix the issues I was having at that time, and I did not know about creating a recovery disc at that time. Any other advise is appreciated.

May very well be a problem with the Broswer. I will assume IE.
Although this tutorial is for crashing, the same principles will hold true.

If that does not work, how about, as a test, try a different browser.
Chrome or Firefox is very nice.
Finally, as a test, try in another user account.
