Running into a problem running Sims 4 Studio (Wishes). Program crashes to desktop with no visible error message. However, looking in the Windows Event Viewer, I see two errors and an information notice. These are listed below:

System runs Windows 10 Pro 64-bit, fully updated, 16 GB, GTX 960m, Core i7 5700hq. Blender 2.76 installed and with a clean Sims 4 folder. Error seems to be an overload in one of the text handlers? Been a while since I last tried to interpret a .NET error stack...

Let me know if you need anything else. Thanks.
