Steam - Game content conversion

[cricketin3d]

So i downloaded P:BP the other day, it worked fine all the way till tuesday/wednesday of this week (its now sunday) i got the same conversion notification. and it would never convert, same for Penumbra:Requiem. after multiple tries for both, resetting my internet, and restarting my computer nothing worked.
i completely deleted steam and all files related files.
i re-installed steam. TF2 and Amnesia reinstalled fine with no problems both fully operational. but both penumbra black plague and requiem would asked to be installed, id accept, and when it was going to install it was stuck on verifying local game cache or something like that.
i did the whole verifying the cache through properties, changed my server, changed ClientRegistry.Blob it ClientRegistryOld.blob and just about every trick i could find.
i even went and purchased the Penumbra Collecters Pack with Overture BlackPlague and Requiem. Overture downloaded fine and is completely operational. but the other two are stuck in Converting to a more effeicent format
Ive sent multiple emails to steams support page requesting either help with the problem or a refund but they havent contacted me back.

i just really want to play these games
