Parts not showing up on drawing sheet

Hello,

I decided to edit the original drawing template so all the info boxes that i don't need would be gone, so i did.

Now is the problem that i saved that edited template to overwrite the original one, so the default one is gone.

My problem now is that when i want to add a part/assembly on my drawing, it doesn't show up, it says the part is being projected on the sheet, but it's outlines are not visible...

What now?
