I bought a license for your product and every time I start my PC it shows an splash screen telling me the "try version"will expire in some days. Ive already bought a license AND it is registred in the software. WTF is happening??? I dont want to be annoyed constantly with that. if i can't solve it,  ill ask you to refund and cancel…
