Since MySpace Advertising has come out, I have had a hard time uploading a custom ad. It occurs when you click on “Upload Custom Ad” and then when you select the ad you want to upload, it quickly loads 50% to “Upload Resource”, and then just sits there and does nothing, as shown below:
I have contacted MySpace about this and they said it is an issue they are aware of and are working to get it fixed. I am on MacOSX – Leopard, and have tried this in both Firefox and Safari. I have also upgraded to the latest flash, but the problem still occurs. So if you have this problem, I guess we just have to wait until it is fixed.
