Datastax Devcenter 1.1 fail to start

问题:

I'm using 64 bit Windows 8. It was fine yesterday, and it just failed to start. It shows the loading screen, but it just stop right there.

Anyone has the same problem? Any fix? It has happened to me twice with my old pc, which were using 32 bit Windows 7.

While I haven't heard of this issue before, here's something that will hopefully fix the issue:

1. find a directory called .devcenter in your user directory (that should be \Users\<youruser>)
2. move this directory to a different location
3. start DevCenter

If this doesn't work:

1. in the same \Users\<youruser>\.devcenter\logging folder find the log.txt file; you might be able to see the root error
2. there is a newer version available (1.1.1)

Some time this can be due to Java version. For me it was failing because I was using Java 9. It worked fine after downgrading to Java8. Confirm compatibility of your devcenter and java
