issues during upgrading before renewing the subscription

Hello, we have this problem. We are going to revamp the CB. Before to renew the developer subscription, we upgraded the latest version of CB, but now, it looks like several items on the site do not work. It seems that several third parties extensions are affected by the CB upgrade. I.g., a specific one is no longer working (it gives us the error: 1146 Table 'Sql1084891_1.#__comprofiler_plugin_activity' doesn't exist referred to CB). Can you help us before going on with the purchase of the subscription,just to avoid spending money in case the new version does not work on our site?
Hoping to hear from you shortly, thanks a lot in advance.

We can't help you with 3rd party extensions, but your error is not from a 3rd party extension. That looks like an issue in CB Activity, which you last downloaded in 2017 so it is not compatible with the latest release of CB. You'll need to update CB Activity to the latest release after subscribing or you'll have to disable it. I can't guarantee it will resolve your issue, but it likely will since your issue is likely entirely due to being due to incompatibility.
