Here is a fix for everyone. Instead of sharing your Mac Address with members of forums to get a file "created" for you, you can follow these instructions I have created and resolved the issue I was facing.

Ok, since I have fixed myself, I will now spread the help, so here is what you do to fix the "Authorization Failure" message within the iVue Guide. Make sure you have iVue Guide Closed entirely before proceeding!

1. Get access to your "addons.ini" file. This might be located in a folder called "tvguidetecbox". If you are on Windows, just use the search function and search "addons.ini", and make sure the directory is somewhere in appdata/tvguidetecbox.
2. Go ahead and download Notepad++ (it's free).
3. Once you have your addons.ini file found, from step 1, Right-Click and "open with Notepad++".
4. Notepad++ will now open and you will see a lot of text. Perform a search for "mac". You should get something like "mac%22%3A+%2200%3A1A%3A79%3A10%3A10%3A10%22%2C+%2 2". Yours might vary, but will look like that. Go ahead and copy that information by CTRL+C. Open a Notepad doc and paste this for now. We will need this later.
5. Now go to:
Code:
http://www.url-encode-decode.com[/url]
and paste (CTRL+V) in the left box and click "Decode URL". You should now see text on the right-side box looking more understandable (should be a Mac Address like XX:XX:XX:XX:XX:XX). Copy everything generated in the right-side box (CTRL+C). Now click the "Start Over" hyperlink to blank out the results.
6. Now again, paste (CTRL+V) and change the numbers/letters (between the : symbol) with your Mac address you purchased from IPTV Stalker folks. Once complete, click Encode URL. Now you have your code on the right-side box which you will want to copy (CTRL+C). Open a Notepad doc and paste this for now. We will need this later.
7. Head back to your open Notepad++ document that should still have the addons.ini open. With Notepad++ Selected, hit CTRL+F to bring up the find/replace window. Click the "Replace" tab. Now from step 4, we need to paste the ORIGINAL encrypted characters in the "Find What" field. Then we need to paste your code (with your Mac) from step 6, into the "Replace With" field. We're almost done...
8. Click the "Replace All" button and then your Mac address will replace the original Mac address, which will allow channels selected with the iVue TV Guide to work and not show the "Authorization Failed" message.
9. Make sure after the replacement step above, you save (CTRL+S) and close Notepad++.
10: Now just overwrite the original addons.ini file with the newly created one you just saved. Open iVue Guide and you should now be up and running again! Enjoy!
