After a serious software crash of our HPLC computer we lost most of our data files, including part EZChrom Elite 3.3.2 files, wich made us unable to restore it. Hard drive format and system reinstallation was necessary. We tried to install again EZCrom Elite 3.3.2 from purchased disk and it ended with success. However, the licence could not be installed, because request code was used once - during the first installation (eight years ago). I would like to ask if it is possible to recover the licence and how to do it? After system reinstallation we decided to change system from windows XP to Windows 7 Pro, but the hardware remains the same - the same PC station and the same HPLC apparature. HPLC is intalled at Jagiellonian University in Cracow (Poland). Where can we look for further help? I wish to say that this is an urgent issue and without it we will not be able to analyze the outcome of our reactions, which essentially stops our work.
Thank you in advance for help!
