I am new to erlang. I installed erlide plugi and When I try to open the Erlang Preferences (Window -> Preferences -> Erlang) I get the following error, "An error has occured when creating this preference page.". I have attached the logs for the error. This is a new workspace I created. It used to work with eclipse Luna. I tried to use it in Eclipse Mars and I got this error. So, I tried to check with the previous versions of eclipse and I am still getting the same error. Not sure what went wrong.
I also tried uninstalling my erlang (erl5.9.1) Could someone please help me what I am missing here?

Thanks, Vijay
I installed the latest version 0.33.1 But, had the same issue. Someone mentioned somewhere about the 'Check Updates' option for a similar issue. So, I tried check updates for Erlide plugin which brought it down the plugin version. I tried this couple of times and each time it brought down the version. Finally I was able to settle with verion 0.31.0 Seems like plugin compatibility issue.
