Error or problem
User interface or workspaces
First, this is primarily a user-to-user help forum, so " us guys" are just other users. No more a staffer than you are.
Second, not much clue what your troubles were because it's not clear what you meant. I will give a couple bits of maybe useful information.
Premiere Pro, like any other NLE, stores what we do in its project database. You delete the project it's gone. The same with sequences ... the data about a sequence ... what sections of what clips, all effects & etc., are stored in the sequence metadata. Delete a sequence, that data is gone.
It doesn't "import" external items like media files really, it references their location on the computer in the project file data. So it never makes a copy of what you've got on disc, unless you have it do that specifically with a detailed ingest process. Basic "importing" of media just means it adds the reference on their location to the project file data.
