Hi!

I made an app in Flex and it works great locally but when I upload it to my server I get errors 😕 YOu can view it at [http://divita.eu/test/virtual\_mountain/](http://divita.eu/test/virtual_mountain/)

```auto
Error: Unable to load ''.

```

Any ideas on what could be the cause of this?

Thnx a lot,
