If you copied and pasted the whole code I gave you then those issues are already solved, except the Author one since I forgot to move it to the [metadata] section. So, please move it from the [rainmeter] section to the [metadata] section.So far the Skin is working without any problems.
I didn't write the code for it, I just downloaded it and modified it.

Anyway, it's important that you understand what is deprecated and what is still up to date. You can copy and modify any skin, but if the skin you're modifying is pretty old it won't work since Rainmeter has changed over the years. Knowing the up to date rainmeter structure is important so you can modify older and newer skins, or even create your own.
"I didn't write the code" is by no means a valid excuse to not fix it correctly.
If you have a "do it for me attitude", be sure that the help you need won't come easily. I did give you the code only because you're a beginner, but be aware that the next time it will be you who will have to think how to solve the issue, obviously with our guidance.
I invite you to carefully read the documentation, and as always, if you have any doubts feel free to ask your questions here or create another topic for it.
