I cannot view the e-book I bought

[joes18414046]

I purchased an e-book which I had to use Adobe Digital editions, was able to open the book, then was told the certificate was not valid, then go another e-book and tried to open it but it will not open

Can you open other eBooks?

the only one i've been able to open so far is the one that came with the software.

I bought a book on Homepage | Wiley  thinking it was going to be in *.pdf format, but it came in *.acsm, and they do no offer refunds.

So I am in talks with them at the moment, but I also thought I would try these forums.

The program gets stuck downloading content.
I run windows 10, and have tried the folowing methods.
Uninstalling and reinstalling, changing registry things based on other advice observed here, unblocking with windows 10 firewall

I would try port-forwarding on my router, but I have no idea what port's this thing uses!!

Very frustrated.
