I upgraded my jsreport server to the new version. But when I start up the app I get these errors on windows. Any idea whats going on?? Funny thing is, it seems to run just fine on ubuntu, but on windows it crashes every time.

I'm using the suggested config for fs-store

{
...
  "store": {
    "provider": "fs"
  },
"extensions": {
    "fs-store": {
      "dataDirectory": "data",
      "syncModifications": false
    }
...
}
