Hello and welcome to the forum!
You can get the latest PODBot version right here, from Bots-United.
If you had read this thread, you'd know it

When you're new, it's a good idea to read some of the "read first" threads first - as the name suggests.
So go to that thread and download the package linked under point 1). It will give you all the files you need.
Now the actual bot dll is the most important file. The complete package contains an older dll, so you will habe to follow the link mentioned under point 2) in that thread to get the latest dll.
Simply overwrite the old one with it, and that's it.
You can get waypoints etc. from the Bots-United filebase, too - just poke around a bit, read some of the "read first" threads and feel free to browse the forums for more information. That's what it's there for.
Good luck with the installation - you will find information on how to install the bot in the PODBot MM forum. It can be a bit tricky sometimes, so if you don't understand what you read or if something's going wrong, don't hesitate to ask.
CU!
