Delete the advertisements?

[JensenBreck]

Hello,

I'm stupid, and formatted an SD card and thus lost a crucial Video Demonstration.

Been looking up ways to recover data, and have tried a few, not many to any degree of workable avail.
I'm looking for a way, to delete the advertisements run history to be able to rerun advertisements later, as if they were never executed on the client.Anyone had a similar problem and found a workable solution .Please help me .

Any help will be appreciated.
Thank you.
