I would have uploaded a screenshot but github says that it can't process the image

It means that your OS doesn't let tracker to access file. You should set up security permissions.

Kender42 commented 4 years ago

It just started happening about 5 minutes ago and now I get this everytime I start it.

How do you set up security permissions?

Razviar commented 4 years ago

Do you have latest version? Try manual update

Kender42 commented 4 years ago

Yes I have the latest version. I downloaded it earlier this morning

I usually get this error when programs try to run from AppData instead of Program Files

[edit] I'm just an End User and not very tech savvy

2 quick possible reasons I can think of

  1. No file permissions. If this was the case, it would have occurred in previous versions also. But it is something you can try on your end @Kender42 Solution 1: Run MTGA Pro Tracker as administrator Solution 2: Manually set security. In explorer right click the folder "MTGA" in "C:\Users\my user name\AppData\LocalLow\Wizards Of The Coast\" > "Properties" > go to "Security" tab> click "Edit" > select "Users (YOUR_MACHINE_NAME\Users)" > select "Full control" under "Allow" > click "Apply" and then "Ok".

  2. Program is reading the log with a too short interval. It's possible that the software/hardware of Kender42 can't follow. Could be very slow hard drive, CPU too busy with others things or anti-virus holding something up just long enough for 2 reads to overlap. It seems when libs like settings-store or json-storage read a file, it also locks the file. So maybe it's a limitation of Electron that files always get locked. And that is the error that Electron API gives if a locked file is trying to be read. In contrast with MTGA pro v1 where filestreams were opening with read-only access and it doesn't matter if 20 processes access the same file at the same time.

Could be a lot of other things but I think these are the 2 main possible reasons.
