My quicken suddenly stopped working 3 weeks ago; it would not load my data file. It was a panic. I spent an hour talking with Quicken support; no help. At the end of the conversation the standard refrain - "we can't help you, it is a Microsoft problem". I was on my own, panic stricken. I experimented and moved my data file to the C drive where my Quicken is located versus on the D drive which is my solid state internal added drive. RELIEF!! It started working.
My million dollar question - when everything was working fine for a couple of years from drive D, why did it suddenly stop working?!
