SQLite no such table, logic error

I had a database it worked fine, I changed the name of the table and it stopped working, if I change the name back, it works again. Of course I change query string after changies in the database. A feeling that SQLIte caches my database... What could be the problem? My query string:

"SELECT * FROM 'tb_Table_Name' ORDER BY 'Id';"

If i change tb_Table_Name to Table_Name it tell me no such table, logic error... And when I add new columns SQLIte not find them too, it tell me no such column, logic error It looks like it just working on my previous database structure. I can't understand why... Help me.
