Are the two stores in a mall situation, sharing cgis? If so it may be that you are not logged into the store that you think you are when you upload the products. Try closing all browser windows and then reconnect to the store you want to upload to and see if you can then upload the products.
Note if you have 2 different browsers (InternetExplorer and Firefox or Safari) you could try using a different one instead of closing all of your browser windows.
