How much time and what was done since the last restore:

Many things can cause loss of Restore Points, when they are gone, they
are gone and can not be recovered or used.
Some of the things are:
Available space on hard drive
Computer usage
Space you dedicate to System Restore

If you use Real Player, try doing without it for a few days:
