Custom Sync - Target Invocation Error

Question

Hello,
I wrote a custom sync that runs fine in my enviornment, however when I port the .dll over to my customers server, I get the following error:
Exception has been thrown by the target of an invocation.
I have searched the internet for advice, and found things related to permissions and other issues, but none that seem to fit.  I figured I would just query the group here to see if anyone else ran into this problem and was able to resolve.
Thanks,
Kristen

This is happening with me too, Shane. Here's some version data:
SAP: 2005 PL 43
Web Tools: 2007 v625
Interop.SAPbobsCOM.dll: 2005.0.0.0
NetPoint.API.dll: 2007.0.625.0
NetPoint.SynchSBO.dll: 2007.0.625.0
And here's the error message that gets thrown by SynchManager:
Exception has been thrown by the target of an invocation.
   at System.RuntimeMethodHandle._InvokeConstructor(Object[] args, SignatureStruct& signature, IntPtr declaringType)
   at System.RuntimeMethodHandle.InvokeConstructor(Object[] args, SignatureStruct signature, RuntimeTypeHandle declaringType)
   at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object [ ] parameters, CultureInfo culture)
   at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object [ ] args, CultureInfo culture, Object [ ] activationAttributes)
   at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object [ ] args, CultureInfo culture, Object [ ] activationAttributes)
   at System.Activator.CreateInstance(Type type, Object [ ] args)
   at NetPoint.SynchSBO.Synch.SynchPlugins(PluginExecutionLocation loc)
This happens just after the objects get loaded into memory from the PRX_Transaction_Queue table, but before the actual data synching begins.
There is another error that occurs, immediately after the data synching ends and right before the SynchNotification begins (looks like it might be the same one):
Exception has been thrown by the target of an invocation.

I'm using two synch plugins, one for Items and one for BusinessPartners. Both of them have been compiled referencing the same versions of the .dlls listed above, the same versions that both SAP and Web Tools use.
