Do certain modules only open in Classic

[phimseto]

I picked up a few Call of Cthulhu items, and noticed that a couple of the campaign books don't open in Unity. Do certain products only open in Classic?

I'm almost certain that they don't, everything made when Classic was still around should still work in Unity and as far as I know Cthulhu only runs 7E so everything made for Cthulhu should work in Cthulhu.
Suggest you
check your account is logging in correctly and updating your purchases
check the products you bought really were for Cthulhu 7e
get a refund if they were not
Send an email to smiteworks support if they are and when you create a 7E campaign are not appearing in your assets to load.

personal I'm thinking you probably just have to update your password and re-sync your account.

I'm sure you're right. The last time that I ran a campaign was a couple of years ago in Classic, so it's been a while since I've had to do importing and setting up. I'll futz around with it some more. Thanks for the detailed response.

All of those should work in FGU and CoC 7E.

If you have FG Classic, re-sync your account. Then make sure to sync your account in FGU.
Here is the web link where you can do this and it should work for both FG Classic and FGU.

1. Launch FGU
2. Create the campaign in CoC7E in FGU.
3. Load the module for the adventures within the Module Activation window
4. For art packs, these don't show up in modules anymore within FGU and instead will be under Assets > Images/Tokens/Portraits

If you have a campaign running in FG Classic, you can copy this folder from your Campaigns folder in FGC's data folder and place it into your FGU data folder under Campaigns. FGU should automatically convert it for play on FGU. This is one-way and you won't be able to sync any new changes back to FG Classic. Your FG Classic campaign will still be untouched in FG Classic, though, because you just copied it. Contact support.fantasygrounds.com if you need any assistance or check with the folks on Discord.
