Yep - its a bug in the latest version (the one that provides Ventura Compatibility) that impacts some users who use e-Invoice and download the payments back into the software.. The symptom is the file, once opened in the new version and then closed, can't be reopened. Its actually missing some header information but the data is intact in the file.
Obviously we are very sorry that this bug escaped our testing. Testing everything is difficult and we are under a lot of pressure to ship the Ventura compatible update. This slipped through.
We pulled the update as soon as it was discovered and have fixed the issue. A new version of the software will be out as soon as possible - I'm hoping tomorrow. The fix is to download that update when it is available and open a backup file.
If you don't have any backup (a backup may have been created when you first ran the new version) contact support and keep the unopenable file to send to them.
