Store not working PLS HELP !

[habab43]

Who helps me gets a reward (LoL acc, or something).
When I click the store ON ONE ACC (Others work great) it says :
- Session Expired (with a Commander Galio skin).
or
- Internal Error Occurred.

PLS HELP. I think its something wrong with the acc

Maybe there is something wrong with the temporary data.
If you don't want to re-install it try this:

- Shut down you pc
- restart it and use CCleaner or a similar program (I only have good experiecenes with it)
- use the repair tool in the lol patcher

If the problem still occours, contact lol support.
