Describe the bug
After upgrading to the latest beta version of romM in order to workaround multi file download issues I am encountering the following issues:

1.) Clicking "Install" within Playnite doesn't result in the rom being installed. Rather, the rom is downloaded into the correct file path but Playnite doesn't believe it to be installed. In order to work around this I have to go into the rom, adjust the path to point at the .bin file and tell Playnite that its been installed.

2.) Clicking "Install" within Playnite results in this error:

To Reproduce
Steps to reproduce the behavior:

1. Go to : Install on a Ps1 Rom
2. Click on: Install
3. Notification within Playnite then shows the error

Expected behavior
I would expect that the rom show up as installed with no error message.

Screenshots
See above

Additional context
I am running v3.8.2-Beta.1
