SQL Server Backup and Restore?

Hello to all,
I've a problem restoring a SQL Express DB.

I've perfomed a Full backup for the db and the logs using SQL Management Studio

I've restored the db backup with no recovery and then restored the logs backup with recovery.

I recieve thi error:

A SQL Point in time restore fails with error 'The log in this backup set begins at LSN xxxxxxxxx, which is too recent to apply to the database. An earlier log backup that includes LSN xxxxxxxxxxx can be restored

If I restore only the db I can't find the data of the last 4 months.

-is this the right procedure or I'm missing something?
