Patch 1.5.1 download problems

i wanted to install the 1.5.1 patch, so i did, but when i installed it it says i needed to have spore to download it wich i had on steam, so i decided to install the 1.6 patch, wich at first worked but then it said that i must download the previous patches before so it tried to download the 1.5.1 patch and it still didnt worked. So can someone tell me what to do ?
