Ok Guys ... after spending all day yesterday puzzling over all this, I have managed to get one of my public Libraries back on ADE, but not with the new version 3.0 or 4.5, my theory with the .ASM file seems to be the problem with 3.0 and 4.5,
I have had to find my old version of 1.72 which I found on www epubsoft.com/soft/adobe-digital-editions, I downloaded this to mty desktop pc, then I went into my Default Programs and Associate a file type or protocol with a program ... open this ... there you will find a file .acsm with the extension saying Unknown Application, high light the file then click change you will then find Adobe Digital Editions ... select that and press change, this will change the ACSM file from Unknown Application to Adobe Digital Editions, then if you open your digital editions hopefully you will be back in some action.
HOWEVER I DO STRESS that this does not work on versions 3.0 or 4.5 for windows, someone else may have some clue but I have not and have not got time to spend another day fiddling, I have Study to get back to .... HOPE this helps some of you and if someone has any other ideas that may help my other library get back on track I would appreciate any feed back for that.
Ok I am back on line with both my Libraries, much of a fiddle, but with help from both Bolinda and Overdrive e-Books I can now access both, how you may ask ....
Download Version 1.72 and link up ADE with the ACSM file this is for Bolinda, and for Overdrive download Version 2.0 of ADE, run them side by side and you will get to be able to access both.
I am happy i have got both my sources back.
Maybe this may help for some of you for you resources.
Good Luck & hope you get your issues sorted soon
