I've already used CSVI PRO for a Joomla and Virtuemart site.
It worked for a long time, then it was down for a few years.
Today I tried to use it again, but I can't import from CSV. The process times out. I should point out that nothing has changed over the years. The CSV generation process is the same as always. I'm attaching an image to help you understand if I need to perform the proposed update.
Joomla is 2.5.17
Thank you for your kind cooperation.
