Problems with EHWIC-4ESG card

i have cisco Cisco 1921 (CISCO1921/K9) and i brouht additional switch card to it but Router does not

support it because of IOS software, i found from forums that software needed is 15.2 ,our cisco is running Version 15.0(1)M4 of IOS. So i wanted to upgrade it but every software i take Cisco CP gives me an error that this software is no supported on your Device, is it okay to ignore the warning ?
