Help with BES

OK. I had perfect syncing with BES and my new Storm for two weeks and then Wednesday it stopped working. I pulled battery, re-activated, deleted my profile on BES and created a new one and re-activated. It worked for about 15 minutes and went down again.

Tonight I upgraded the Storm software to .75 and did enterprise activation over the air from home. Worked fine and for another 15 minutes I was up. I'm down again on the new software.

I'm a small office with only me on the BES and my administrator can't figure out what is wrong.

Any help or advice would be appreciated.

Thanks!
