Hi, A lot of users has the same problem. I have Suitcase 7 (before 6) and Illustrator CC 2015.0.0. I try the following steps below but still same issue. Without auto-activate a document is open in 10 seconds. With Suitcase it takes 45 seconds. For PC there are no other options like another software. I need Suitcase but it does not work.
By the way. saving this documents takes more than 3 minutes
In your Extensis Auto-Activation Preferences, turn off the setting for “Pick the best match when original is missing.” To access your Extensis Auto-Activation Preferences, launch Photoshop and then click on File > Automate > Extensis… > Preferences…
Update to the latest release of Photoshop CC2015.
If you continue to experience performance issues after following these steps, please contact Extensis Technical Support.
