Hi Mark,
I just installed an evaluation version of 11.1 Advisor for purchase over a 10.6 eval. I installed the 10.6 just to get a feel for the software and constructed a few real accounts with historical data. Ok, fine, that was a few months ago.
I have the .mm4 and the .dat files on a shared drive used by two machines.
On one machine, I get an error on startup that says I'm missing a .dat file. On the other, I get no such error.
By my best read of this, I am indeed missing a .dat file because one account contained that investment and shows transactions for that security in the data table for the the account.
How do I fix this?
