WTH?? Cant even get past the 1st screen

I just paid and downloaded this app and it already doesnt work. Will not let me enter any info about myself and wont let me continue with the info I CANNOT ENTER! Does anyone know if there is a help desk or anything? Went to the website listed and its not legitimate. Thx
