You are not in any immediate danger. Have you checked with Windows sys restore whether the restore points are there or not? I'm sure you will have one restore point at least so you have some emergency cover. You can create another point or wait a day for Windows to do it for you.
There have been some comments on this in the past, I can only remember that ticking the Empty Recycler box seemed to be one suspect, but I thought that had been fixed. You could search the forum for info.

I had the same experience wiping free space; lost all points including the most recent. I immediately created a restore point and searched C drive for any other lost files; could not find any. Have used this feature successfully twice before.
If "some time in the past" was more than 90 days (the default maximum retention), the restore point probably would have expired anyway. Also, depending on the size of your drive and the percentage you allow for System Restore (12% is default), you might get significantly shorter retention time.
If you have your product key or other proof of purchase, you shouldn't have to pay to reinstall. Contact the software vendor and explain what happened.
