As we already mentioned before, a new compatible version of IncrediMail 2 with Windows 7 will be released next month. Until then, I can only suggest you to delete your 'Runtime'
folder and check if the issue was resolved.
The problem you are experiencing can usually be solved by deleting your IncrediMail 'Runtime' folder. This folder saves all the recent content that you have used, allowing IncrediMail to reuse the content you have already used, without reloading it to your computer's memory, losing time and computer resources.
If you delete this folder, it will be automatically recreated and the IncrediMail content will begin to be saved again.
To delete your 'Runtime' folder, please click here
Click 'Run' in the File Download dialog, click 'Run' again when asked to run the software and follow the instructions in the SupportUtil dialog.
