Quicken loses the security prices after closing and reopening the program

I’m using quicken 2006 which has 20 years of data. I’m running it on windows xp via parallels on a Mac. I had to get a new iMac. I found when I loaded my back up on to my new Mac my quicken file opened ok. However when I close the program and reopen it all the security price history is gone. Does anyone know why this is happening? I have to use quicken 2006 as I’m in New Zealand and can’t get any replacement. Quicken has been brilliant for me over the last 20 years. Just hope I can sort this issue. Ive tried validate but that doesn’t sort the problem.

I did try holding the control and 4 button as well whilst in an investing account and that reinstates the prices where there has been a transaction but it doesn’t reinstate the historical security prices that I’ve loaded manually every month. Does anyone know why this is happening. I may have to try a different program.
