Error creating Erlang project on eclipse through Erlide plugin

Question

I ran into trouble when trying to install the Erlide plugin in eclipse for Erlang using the guide below: "myadventuresincoding.wordpress.com/2009/02/11/erlang-getting-started-and-using-eclipse/"

and I have successfully installed Erlang on my PC and was able to link the binary files to the system "PATH".

However, when it came to installing the plugin on my eclipse Indigo, it first I could not find the repository: "http://erlide.sourceforge.net/update". But that easily fixed by changing the repo to "http://erlide.org/update" which give a list of tools to download, which happened seamlessly.

And this is when I started to wonder: "Could it really be that easy ?".

My doubts were soon confirmed when I went on to create a new project (File > New > Project... > Erlang > Erlang Project), which immediately gave me an error box of "Unable to create the selected preference page. An error occurred while automatically activating bundle org.erlide.ui (317)."

I've been googling this issue for a while now (~3 hours) with not even a hint to this issue. Is there anyone who has encountered this issue before ?

Here is the error generated from it I hope it helps:

Thanks guys !

I believe that you are using R16B03-1 and in that case you should use the latest beta (0.25.0) from http://download.erlide.org/update/beta. Please let me know if there are other problems.
