After a recent fullish attempt to change my home folder's name (new in mac-had no idea

) i have tried to recover it doing all these actions i found in forum's help section.
Nothing has changed although i followed the directions the best i could.Now im able to use my mac through another account.
I wanted to ask u if ther is aproblem when using only this account and not the admin one.
And i would realy appreciate if someone could repeat the recoveringg procejure step by step as if u were explaining it to your 10 year old nephew.
Thank u in advance!
