Hi,
- CSVI Improved is a standalone Joomla component and works in the joomla-backEnd, but SportMart is a template, works in the joomla-frontEnd. They won't interact each other. So, CSVI Improved will work perfectly fine with SportMart.
- SportMart comes with a 6-months free update option by default. Meaning, you will be eligible to get free updates for 6-months. Approximately within 2 weeks, the new version of SportMart will be released, the development has been completed already, it is in the testing process now (we will send a notification email to all SportMart buyers when it is available -- or you can check our website frequently to be notified). it will support J3.x+VM3.x. You will be eligible to get that new version and will continue to get the further updates for total of 6-months (starting from your purchase day)
regards.
