on entering a code it told me that the code was invalid. I can press ok to enter a code or cancel to take me into read only mode. After entering the lite code its popped up and said that Insite has detected an invalid PC date and has been locked into read only mode and is asking to verify the pc date and time. It then asked if I wanted to enter functionality codes, I assume these to be the lite, pro, codes etc. I just knew this was going to go bad for me ! Ok, so I've set the date to 1st Jan 2014, I assume this is correct ? I've then reinstalled insite 7.6.0 updated it to 7.6.2 Ive entered the first code, thanks to shadowcar, and all seemed good.
