a) First off, you need to clear your browser Cache and Cookies
b) This tutorial will walk you through on how to manually reset your IP address first, if you are still unable to download videos through megaupload due to download limits.
c) If resetting your IP does not work, then the second part of this tutorial will show you how to change your IP address. (Changing IP address via router, shown using linksys router. Should be similar using any other type of router. If you are unsure of how to access your router setup page, refer to your manual or utilize http://www.google.com)
Clearing your browser cache and cookies
Step 1. In Firefox click "Tools" from the menu bar, Then click "Clear Recent History"
Step 2. Next a window will pop up, make sure you select "Everything" in the "Time range to clear:" section, next make sure only "Cookies" and "Cache" are selected. After you have done that click "Clear Now."
Resetting your IP
Step 1. Click your start menu button, then click "All Programs", next click "Accessories", next right click "Command Prompt" and finally click "Run as administrator" Make sure you click yes if a message box comes up asking you to allow access (example shown below)
Step 2. Once you have command prompt open, Type in "ipconfig /release" (without quotes) and press Enter
Step 3. After completing the prior step, next type "ipconfig /renew" (without quotes) and press Enter
Step 4. After completing the prior step next you want to clear your DNS Cache, type "ipconfig /flushdns" and press Enter
If clearing your cache, cookies, and resetting your IP do not fix your Megaupload download limit, then you might consider changing your IP address.
Changing your IP address by changing your routers MAC address (As noted above, this is shown using a Linksys router)
Step 1. Open your browser and point it to "192.168.1.1" Press Enter
Step 2. You will be prompted for a password (when using a Linksys, leave the User Name area clear.) The default password for a Linksys router is "admin" (without quotes) Press Enter
Step 3. Roughly in the middle of the menu tabs you should see a tab labeled "MAC Address Clone" Click this tab.
Step 4. After you clicked "MAC Address Clone" a new page will appear. First make sure you click "Enabled." Next Click "Clone My PC's MAC." Lastly click "Save Settings."
If after following all these steps and you are still having problems, I would suggest that you consider purchasing a premium Megaupload account. Premium Megupload accounts are available at a discounted price over at our partner site Megarelease. Click here for more information
