It might be a problem with the authentication server. Maybe try again later.

Why would it need to do that anyway? Its not a subscription service?

It's not. Photoshop didn't do subscription until after CS6. So it does not require online service at all.

Scrivener used to do that to me. It was all their end. They all want everything to phone home on a regular basis.

so what should I do? just wait a day or two and see if it resolves itself?

I do not know. I’m not in postion to do internet searches rigjt now. With Scrivner Inhad to keep puting in the the serial key until they fixed the bug. Which now that Insay that I realize itks similar but not same problem I had.

Has support gotten back to you?

I haven't messaged them yet. I figured they'd just say 'that program is so old, you need to buy the new subscription service'.

They might but I haven’t seen anything like that. Might ignore you, but then again places do that for their current product.

(I haven't touched CS5 in a long time but) Looking at Adobe's site, it keeps saying to uninstall and then reinstall. Then another section says after uninstall, reinstall as trial version and then input the serial key.

Ok i'll give that a try when I get home. Thanks.

That isn't good. I have CS6...

is yours still functional? i'm hoping it's just some fluke of windows and not that Adobe has done something.

did you do a windows update recently? i know windows has some security issues with the latest updates that mess with programs. currently i had to learn clip because my cs5 has alot of issues working while i run other programs and i have 16 gigs ram, plenty of storage, and radeon graphics. what sucks is my photoshop is getting so old that i fear i may not be able to use it on anything past windows 11 now and will have to dig out and old laptop to make it work fine for some art thats still in psd format. everything new is getting done in clip since i could afford the last version before they do subscription. that might last me another decade maybe. lol

Look in vitural machines. Not easy but an option.

I did check on that but no, there hasn't been a recent update. So not sure what's happened. I really don't want to have to learn another program. I'm too stressed out already as it is.

I have exactly the same problem since yestrerday, also with CS5 collection.

But there was a Windows Update just before the problem started.

Let me know if you find any solutions.

I did get it resolved. I had to contact their customer support. They were able to give me a new serial key but I had to prove my 'purchase', thankfully I still had my box.

Mine is still up and running.

Good to here! Hopefully it won't have any issues :)
