Znode Storefront™ - Dashboard v5.1.1

I'm trying to use the data manager to upload information but I just cannot get it to work.

Ok on my Storefront I have these Categories in my Data Manager. nothing else.

Data Manager Questions
PROBLEM 1: When I go to upload a edited inventory.csv that is in the SAME format as the csv file that i downloaded from Download Inventory. It returns this error "Failed to process your request. Please try again." every time that I've tried to upload it. Another question that I have is do i have to upload a csv file with ALL information or, if i just upload a file that was the addon only will it just delete the database and upload that file only?
PROBLEM 2: When I go to upload an edited pricing.csv that is in the same format as the csv file that I downloaded . the only difference is the added values just like in my inventory.csv in problem 1. It returns the error i put below.
PROBLEM 3: Because there is no Download Products, I do not know the format of the csv file that i can upload.
PROBLEM 4: same promlem as problem 3 i don't know the format.

I would love to just look at the documentation on how your data manager works but honestly whoever wrote it did not bother to explain its functionality.

also i am attaching 4 files of my csv. 1 is the downloaded inventory 1 is the downloaded pricing, 1 is the edited inventory and the last is the edited pricing. I renamed them as .txt because I was unable to upload the .csv file. also i added then new before inventory and pricing to identify which are the edited files.
