Jump list Thinkvantage Tools disappeared

[Edmond Dantes]

I have an X301 with Win 7 32b. The first day it came, I noticed the icon of Lenovo Thinkvantage Tools (3 red spheres), and its jumplist (right mouse click), wich tracks the system foders recently visited.
So I started using it, listing my most used folders in this jump list.
Today the list disappeared without reason. I did no update or whatsoever.
The same happened months ago with the jump list of Adobe Acrobat, and this was never solved (luckily my company upgraded to Acrobat X).
Has someone suggestion to solve this issue?
Thanks and Regards

Sorry, I just found a solution, which with Acrobat did'nt work.
Here it is:
- Open Windows Explorer .
- Type or copy and paste the following into the address bar: %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
- Identify files that are comparatively larger in size than the rest of the file, such as files that have file size of 1 MB or more.
- Delete the abnormal file.
