ACSM will not open

[anthonyv1046283]

My old HP (Windows 7) gave up the ghost (and resides now in the city dump) and I bought a Lenovo (Windows 10). I downloaded the latest digital editions from the site and installed it. I used "add to library" to read BigGoldBookofLatinVerbs555Ful.acsm but got the message shown below.  I have already tried three times with the same result. Can anyone help, please?

Incidentally, I am 73 years old and have only one computer: this Lenovo laptop.

I’m having this problem too

I shall try just one more time to get Adobe's attention:

My name is Anthony Vella from Ottawa, Canada and I am the OP of this thread.

I have never had more than one laptop at a time.

I have just bought a new laptop and all programs are working fine except one: ADE.

I have downloaded and installed (three times) the most recent version of ADE.

I have also installed a previous version of ADE and got the same alert.

I purchased BigGoldBookofLatinVerbs555Ful.acsm through Paypal on 9/2/2013.

I WANT IT TO WORK - MAKE IT WORK!

I don't want to see this alert any longer:

Thank you.

I'm the OP of this thread.

Can someone be kind enough to tell me from where I can download an even older version of ADE, say 3.something? Thank you in advance.
