Hi,
The HikaShop 2.3.3 package is the same than HikaShop 2.3.2 except for the security and the Joomla 3.3.4 patches.
You told us about a problem and I remember that we got a trouble in the starter package which could explain such kind of trouble ; but I'm not saying that it is the problem.
Currently we do not have any access or details to explain what the problem is, I just made a speculation on something that we solved recently which could probably make the same kind of problem.
For the moment, I do not understand your last message, I do not know about what you're talking about, the HikaShop version you were using before the 2.3.3 update, what is the real problem with the download of the CSV, if you got some error message in your PHP error log, etc.
Please understand that I just made a speculation on a possible idea for the idea of the problem you got.
If you want to help us to help you, we will require more details about your configuration and maybe some accesses to see the problem directly.
Regards,
