Hello Damian,
We are provided with the evaluation version of optisystem 14 for one month, But after expiry of the duration we are unable to open those files which using older version, This is a big problem for all the designers. Please provide with some way to solve this issue. if possible provide so way to convert them to make older version compatible. this is because for us licensed users of optisystem 13 are also facing the problem. Ok there must be some improvements in the optisystem 14, In my case I can design the whole system using V13, but from your side I am forced to buy the same soft at a 40% of previous value (told by Gigasoft India). Atleast there should be some way for the licensed users.
Thanking you.
Regards,
Dhiman
