sorry to hear you had such trouble the cakewalk store and steam store are completely separate entities, and all the steam DLC ("content") product pages do clearly say "This content requires the base application Z3TA+ 2 on Steam in order to run." did you post in the relevant steam forum?
yes they are completly different which is bad anyway you can not mix steam things with regular ones .
to be a little bit clearer this time . to take advantage of the steam sale and some content i have buy Sonar Home Studio which includes Rapture Session . in this way i have also buy "Digital Sound Factory - Analog Bass Synths" which are for Rapture Session which are included within Sonar Home Studio . i went over to the steam client and have buy "Cakewalk - Sound Center Pack Complete Bundle" , on the description page on the Cakewalk - Sound Center Pack Complete Bundle are clearly written "
Must own Music Creator or Sonar on Steam to use this add-on" so i have buy because i have buy Sonar Home Studio at the same time . but Steam or Cakewalk means that Sonar Home Studio are not Sonar . Sound Center are discontinued by Cakewalk and replaced by Rapture Session which can open Sound Center Expansions . after i noticed that i can not download the Sound Center Bundle i went to the Single Expansions Page where are written now "this Product needs the Basicsoftware Cakewalk Sound Center on Steam" which are not written on the Complete Expansions Package otherwise i had not buy this . thats why i said before it is not clearly described on the Sound Center Bundle . i have no idea why they made it this way or changed it .
not to forget about the rapture session install on steam which mess up regular Cakewalk versions and that you can not connect it via Command Center .
no i didnt wrote this on the Steam relevant Forum . i written it here to the Support on Cakewalk . i dont know how long it takes before the Support answeres , otherwise i may needs to write on the Steam Support and take the money back (which i basically dont want , i just want to become the product i have buy) .
i hope it is a little bit clearer now "the Story behind" .
