Adobe PDF DRM Is Hell !!

I bought many eBooks at many Online eBook Stores and I can read them in my desktop computer. I tried to copy them to my laptop computer and I got errors related to the DRM (Digital Rights Management) [Adobe Reader]. The only solution I found was downloading each eBook again (each [login to view URL] file), from my BookShelf, to my laptop. The problem is that my BookShelf is large, so it takes to much time to download each eBook again. My question is - Is it possible to backup/restore DRM between different computers ? I would backup all DRM settings from my desktop PC and then restore them in my laptop PC, avoiding the re-downloads... Is this possible ? Another option is decrypt the pdf files (reset security settings / drm). My knowledge about this subject is not great… I tried many google searches and I could discover some important keywords, that may help you : “Electronic Book Exchange??, “ebx_handler??, "vouchers", “pdf cracker owner password??, “Dmitry Sklyarov??, “Hidden keys to software break-ins and unauthorized entry??. Please note that I am not a “bad guy??, I do not want to make illegal copies, or something like that! I just want to use freely the eBooks I have legally purchased!! Thanks in advance.
