I recently purchased 5 ebooks directly from a publisher's website and downloaded the .acsm files onto my desktop. When I try to open the books in ADE, only 2 books successfully opened. When trying to open the other 3, I receive the following error message
Error getting license
Server communication problem: E_ADEPT_DUPLICATE_TRANSACTION_ID
Does anyone know how to solve this? I've tried deleting the files and redownloading and I keep getting the same error. I've been able to download files from this publisher before and was able to transfer the first 2 books onto my Nook. One other thing to note is I was able to open all 5 books on a different computer (before getting these messages on this computer) using the same ADE account and had no problems.
Actually in this case this was a server misconfiguration on the seller's side ( they were re-using the same "Transaction ID" ). You will need to contact the seller to get a new link.
