Hi, On 2nd April 2016 I bought online from Simmarket, FSUIPC4 (Update/Discount) with FSUIPC4 Key XXXXXXXXXXXX. Whilst downloaded and saved I did not attempt to install until early May. Then on your forum I found the product update Version 4.95 of FSUIPC4.dll. replacing that on my April order. Downloaded v.4.95 and installed with my FSX Gold Edition without any apparent problems and installation went OK. However when it came to registering my Key was rejected. Which presented me with the following questions :- 1) Do Keys expire after a limited time ? 2) If not then why cannot use it on the latest v.4.95 ? 3) I cannot open the Key file in the FSX Modules folder. What common text editor will work? Hence confused, although years ago I had FSUIPC on FS2002 & 2004 which ran without any hitches and was brilliant. As I'm now 75+ I must blame this current problem on my age/and Modern Computer running Windows 7 - Pro - 64 bit.. Tried to forward a copy of my install log but was refused. Hope you can assist, so I can 'fly' again. Thanks
