RSLogix Start up Crash

previously my RSLogix was working fine, but after installing pannelbuilder32, RSLogix won't start up anymore. I have tried uninstalling all Allen-Bradley software, and then re-installing RSLogix and I still get the same fault.

When I try to start it, I get a message that says "RSLinx Communications Server: RSLins communications server has encountered a problem and needs to close"

This is followed by a message that says: RSLinx.exe application error: The instruction at "0x10003ad3" referenced memory at "0x3f420c0b". The memory could not be "read"

I am running windows XP SP2, RSLinx 2.41 (rev10), RSLogix500, and Pannelbuilder32.

Windows XP SP2 -- pro or home??

Home

I don't believe any RS Software is "officially" supported in XP-Home.

It isnt supported and 2.41 is too old for XP in the first place go with 2.43 or better and win XP Pro SP2

but it has been working for months.

That is the trap with XP Home... it can work for a while and then just stop working for any or no reason...Home is not stable.

You have to look at it as " it worked for a while even tho it shouldnt have.
