How do I get back my Microsoft Restore Points after installing AVG PC Tuneup

I have Windows 7 Professional and ALL MY RESTORE POINTS FOR WINDOWS 7 HAVE DISAPPEARED!!  I was being VERY careful to configure AVG PC Tuneup because the last time I installed it I kept getting this error: "The Rescue Center has stopped working"... with no way to restore from your Rescue Center I went to Microsoft Restore and was HORRIFIED to discover that AVG PC Tuneup had REMOVED ALL MY RESTORE POINTS!!!  As a result I have had to spend TWO WEEKS installing an image disk backup... but since it was from a year and a half ago I have lost many things.  I have Carbonite backup and thought I was covered but I lost a presentation I have SPENT TWO MONTHS WORKING ON (it used non-standard files and was stored in its own folder so Carbonite didn't back it up)... all because I couldn't do a simple RESTORE (all Microsoft Restore Points were gone and when I turned to Rescue Center for help (Undo Changes) it just said "Rescue Center has stopped working"!  

I was VERY careful in configuring AVG Tuneup this time, to avoid this, but when I just took a look to see my Microsoft Restore Points, they are once again GONE!  If I can't install AVG PC Tuneup without disabling the Rescue Centers takeover of Restore, then I'll be uninstalling and asking for my money back!  Hope someone can help as I really like the performance boost AVG PC Tuneup gives.
THANKS!
