WORKSHEETS ARE GONE

[Anonymous]

So I'm a newbie in Archicad. I don't know what I've clicked but my dwg on worksheets are gone. The last thing i remember is clicking the layout tab and when i get back to project map, i dont see anymore worksheets. I need those because i am tracing a project from it. I restarted the program and its still not there. I also tried adding new independent worksheet and attaching xref and its also not showing. What have I done? Please help me. This is due on June 30. Thank you so much.
