Without proper system information and other technical details nobody can tell you anything.
I'm sorry... here it is.
Its notebook Toshiba p750-15c
Intel Core i7 2670QM Sandy Bridge, 15.6" LED TB 1366x768, RAM 6GB, NVIDIA GeFoce GT540M 2GB Optimus, HDD 640GB with windows 10
Until now it worked normally...
So what changed? Something did. System update? Virus Scan Update? New Font? AE Update? If an app that was working suddenly stops working then either something changed on the system or you have run out of disk space or you had a component failure.
I dont know... :// So I reinstal windows back to win8 and now it work! Thank you for your answers!
