I am sorry to hear that you have experienced this problem. Unfortunately, the first problem seems to be a bug in the current CS-Cart Ultimate Edition version. A fix to this problem is quite complex, so you should better contact us via Customer Help Desk and provide temporary access to your server by clicking on the Add record link on the Access information page of your Help Desk account so that we could fix this issue directly on your server.
As regards the second issue, unfortunately, I cannot tell why it occurs. Our technical support engineer will also examine this issue in detail and let you know the result.
