Did you have Abe's Post Thank You Hack installed? If not, then running the importer is unneeded since that's what it does.
To ensure you can see the DBTech - Post Thanks group, ensure your userid is added to the Super Administrators variable as per this documentation page:
https://www.vbulletin.com/docs/html/..._is_superadmin
If it still doesn't show up, then please try re-importing the XML file or re-uploading the files with SmartFTP (to ensure there aren't more 0-byte files creating issues).
To answer your specific question, running the importer before step 3 would result in a different error, as the database tables for this mod would not have been created
To address your post pre-edit (it shows up in full in the email notifications we receive to this thread):
I apologise for being short. I don't mean to presume you (or anyone else) are stupid, which ironically is why I'm short.
See, I'm terrible at teaching people. Just ask any of the other coders on our team that I've had to advise. Being that I know what I'm talking about, I have huge problems explaining it in layman's terms (and especially in terms of someone who has
less coding knowledge but not
no coding knowledge, in the example of our other coders) and as such, every time I go into more details I feel like I'm treating the other party as being stupid.
Hopefully you can relate with your area of expertise.
Again, I apologise, it was not my intent to cause frustration
