Suddenly unable to add rows

[Juanava]

Have been adding an alphabetized list to excel with multiple columns. Have been able to insert multiple rows until this morning. Now, that option is greyed out. 

How do I get the function back?

Thank you!

Hello,
To solve the problem, let assume your data span between A1:G100 goes down to row 100.
1. Place your cursor in cell A101
2. Execute Ctrl + Shift + Right and Down Arrows.
3. Right-click on delete the entire selection.

That should solve the problem
