Has anyone else experience this problem?
Please help.
EDIT:
I tried copying the project to another computer it seems that the project itself is “corrupted”? the services window is missing I don’t know how it happened but no matter where I try to open the project it just seems to be broken.
I had the same problem (IAP error regarding StandardPurchasingModule AND services window missing), here’s how I fixed without needing to copy & paste anything via explorer.
I deleted Plugins/UnityPurchasing folder
I closed Unity
I opened Unity and clicked Window > Services (now SERVICES tab was open)
Via SERVICES tab I enabled Unity IAP
I clicked IMPORT and selected all
!!! THIS !!! Insider the Plugin/UnityPurchasing folder there was UnityIAP scene. I clicked the scene.
UnityIAP scene asked me to import stuff, I clicked OK
=> now all the missing Bin, Editor, Icons etc folders were imported fine. No IAP errors. Service window was back and stuff started working OK
Protip: don’t go offline / lose your internet connection while the Unity Editor is open
I just experienced the same thing on 5.5.1 f1, so I upgraded to 5.5.2 f1, but no dice. I also am just getting blank panes from time to time in the inspector and the project pane. Anybody seen that before? This sucks. I was hoping to get another release out soon for my game and then this just started randomly breaking.
