The problem with the DRM...I have an unusable PDF lying around on my HDD, it is a DRM file, purchase at one of the the several sitest that sell them (not Amazon) and it doesn't work anymore because I formatted my HDD and now I have no idea how to "reactivate" the PDF file.
I tried some kind of DRM remover called Advanced Password Recovery I think, but it said it didn't support this mode of protections...so you can fail at trying to "open" the PDf you own.
Maybe another program could have done the job, but so far I haven't found anything that looks promising.
