I've been having this problem for the last few days. every time I turn on Qwin, it says this
after I use "Open a data file located on this computer" and select the main file on my drive, it will load. but next time I close and reopen it happens all over again.
what I tried was after successfully reopening the file, I saved a local backup. Open the backup, and the backup file created a main file.
the next few times I open Qwin it worked fine. but it's just again prompted me that Qwin can't open my data file…
I've never encounter this before…. I've been tinkering with Qwin a lot lately and the more I use it, the more random things will happen. for example, right before the most recent "can't open my data file" happen, I was looking at one of my brokerage account, and for the first time ever, the transactions were no longer correct. thats' why I closed Qwin and see if I can load an older update to fix it, but it then told me can't open date file….. it seems the software is very unstable?
