Note able to delete a page, it restores back

[acerNZ]

I have a issue with notepad++ one of the pages whenever I delete, it throws up dialog box, “Error the old session witll be restored” is it because, I messed up or some lock I did I did not know ?
Finally I had to unistall and install again to get rid of the issue. Please can some one advise me why that issue has come and how to fix it, if I do not want to uninstall and install again ?
Regards
