Yes, I tried 3 version. I figured it out that in the process of installing the first time, it messed with my java. So my sidebar didnt worked either.
So I reinstall the java and its working.
But now I have the problem that it won't sync because it request to connect to the internet. I saw several thread on this already and now using v4.7 with reg edit to solve the problem in the mean time. Looking for a solution for v5, but yet to find any.
Sad that RIM don't fix this problem.
