Motec and ACC

Installed i2 Pro
Followed steps to get ACC workbook into Motec
When I click the data folder it defaults to C:\users\GRENKE\documents\assetto corsa competizione\motek'
However there is NO USER called GRENKE so where on earth has it got this from???
So I have to have to navigate to the correct folder grrrr
Also when looking at Histogram properties how can I save the setting so I dont have to keep inputing them?
