After select admin theme, can't open admin panel

Warning: Smarty error: unable to read resource: “index.tpl” in /home/surway/public_html/lib/templater/Smarty.class.php on line 1095

how to solve this problem??

Didn't think you could select an admin theme other than 'basic'…

Restore index.tpl.

I tried to restore the index.tpl in /www/skins/basic/admin/ but still not work.

We purchased a theme from cs-cart offcial partner a month ago and today we select theme at backend, there is an option except basic/ for admin. But after we selected it, we can't login at all, the page turn to smarty error page. We asked for help from the theme seller but they are impatient to help. I am so disappointed with them and with cs-cart. But I still hope to have a try.

One more thing, is there any HOSTING REQUIREMENTS FOR CS-CART? Like CPU/ MEMORY limit? We use a shared hosting from HOSTGATOR with DEDICATED IP/SSL. Is it enough?

I used many shopping carts but it's my first time to meet the problem CAN'T OPEN/LOGIN ADMIN PAGE.

thanks problem solved by support team. the problem is caused by theme.
