Quicken 2008 Deluxe in Windows XP.
I developed a problem with my Quicken file. I download my transactions once a month. This month, all the transactions from a certain broker did not download. Quicken says "last download 12/3" but nothing downloaded from that broker since 11/3. All other accounts downloaded fine. I created a test file and tried downloading again from that broker and with the test file this broker's accounts downloaded fine.
So I am assuming my Quicken file has become corrupted somehow and I am not sure how to proceed. I do have backups but that may mean re-downloading 2 or more months of transactions (because I had to download twice on 11/3 to get that broker's transactions to download) from all brokers, credit cards, etc.
If I validate (how does one "super-validate" if necessary) how would I know what changes the validation made and might that not mess things further? Anything else I should try?
This file has many years worth of data.
