There are several reasons why this can be happening. Please check the following:

Clear Your Browser Cache

You need to clear your web browser's cache to be sure your old files are not being shown. Many browsers are set to display a file that is saved on your hard drive "cache" and not directly from the internet to speed up web surfing. By clearing your browser cache, you force the browser to load all new files directly from the internet.

Internet Explorer 6.x

1. From the Tools Menu, select Internet Options.
2. On the General tab, click the Delete Files... button.
3. Click the OK button on the popup window.
4. Click the OK button on the Internet Options window and then press F5 in your browser to reload the page. *

Netscape Navigator 7.2 & Mozilla 1.7

1. From the Edit Menu, select Preferences.
2. In the category list to the left, find Advanced and click on the [-] icon next to it to expand the list of Advanced Options.
3. Click on Cache.
4. On the top right side, click on the Clear Cache button.
5. Click on the OK button and press F5 in your browser to reload the page. *

Firefox 1.0

1. From the Tools Menu, select Options.
2. Click on the Privacy Icon on the left.
3. Click on Cache on the right and then the Clear button.
4. Click on the OK button and then press F5 in your browser to reload the page. *

* NOTE: If this doesn't work, you might try holding down the CTRL key while pressing the Reload icon on the top toolbar of your browser.

Internet Speed-Up Utilities

These utilities will enhance your web browsing speed by caching (storing) visited web pages to your hard drive and displaying those pages in your browser instead of directly from the internet. If a page is changed, the utilities may not always update to the new page. You will need to find out how to reset or clear the cache of such utilities before your new page or file can be shown in your browser.

Internet Service Provider's Enhanced Speed Services

Some ISP's also provide a service for free which caches web pages on their own proxy server and shows them to you on your browser. In some instances, you can hold down the CTRL key and click the reload icon in your browser window in order to force the new files to be displayed. If this doesn't work, you may need to call your service provider's technical support help line to obtain further help on their service.
