SLES8 on Novell "Linux Technical resource Kit"

Hi everybody I installed a SLES8 from the isos contained on one of the free dvd from Novell. My question is: Is that version crippled in any way? i mean, will it stop working after one month or something like that? i couldn't find a readme telling that, but i always doubt about 'evaluation software' (YKWIM). Thanks in advance LeoR
