App licenses not syncing (Windows 10 preview desktop)

[TripleHelix192]

I'm not sure if anyone else has noticed this, but I my app licenses aren't synced properly. I bought Tubecast via IAP which isn't being recognised as purchased on my Surface running Windows 10 preview 10049, and now after buying Halo Spartan Strike, shows up on my list of purchased (but not installed) apps, but when I go to install it, only gives me the option of buying it.
I haven't read anything about others having this issue, and I only noticed it after updating to this build (TubeCast was unlocked in the last build).

from the run command (windows key + r) enter tpm.msc and hit enter.
If you have any other statement other then "The TPM is ready for use." under status then you will have to clear the tpm. If you have bitlocker encryption enabled make sure you disable it before reset.
