I have tried synching my x51v using AS 4.0, 4.1 & 4.2 on a laptop Dell D820 (one week old) using USB, IR & BT but when i connect I instantly receive an error "Activesync has encountered a problem and has to shut down.....", then DrWatson PostMortem Debugger chips in with a similar message after you click dont send on the Activesync Applition error.

I have uninstalled on many occasions and reinstalled in normal and safe mode but it doesnt work. I am able to sync on a desktop with ease (all machines have XP Prof SP2 installed). Both pcs have more or less the same software except that the laptop is a work machine on a domain. I was able to sync now and again on the on the previous work machine a Dell C840 last month (same softwares). The D820 Laptop recognizes the x51v and connects but it does not complete the partnership, I am up to Mobile Based-Device #8 in Device Manager under Network Adapter because on the many installations(is there anyway to prob delete the previous entries and let Device Manager start over at Mobile Based-Device #1). I normally delete the mobile device under the connection settings before i try to reconnect.

Any help would be really appreciated.
