CommNet breaking in GPP

[Jebediah Kerman Jr.]

A lot has changed since I last posted here. I've now set myself up with a PC and installed a number of mods, including Galileo's Planet Pack (which is terrific, by the way). The pack adds many new outer planets, unreachable with stock antennas, so one of the R&D nodes adds antenna upgrades for the Communotron 88-88 (the umbrella one) and the largest of the relay dishes, which are now rated for 1.00T instead of just 100G. Ever since I researched this node, the CommNet just breaks every time I launch a vessel from the VAB. The craft on the launchpad has no connection to the space center whatsoever. I go to the Tracking Station and the CommNet lines are gone. The logs are absolutely filled with spam, but here's one section:

[EXC 19:26:17.574] ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index System.ThrowHelper.ThrowArgumentOutOfRangeException (System.ExceptionArgument argument, System.ExceptionResource resource) (at <ad04dee02e7e4a85a1299c7ee81c79f6>:0) System.ThrowHelper.ThrowArgumentOutOfRangeException () (at <ad04dee02e7e4a85a1299c7ee81c79f6>:0) PartModule.ApplyUpgradeNode (System.Collections.Generic.List1[T] appliedUps, ConfigNode node, System.Boolean doLoad) (at <2afc64dea36946459d4707808bdac511>:0) ModuleDataTransmitter.CommPowerUnloaded (ProtoPartModuleSnapshot mSnap) (at <2afc64dea36946459d4707808bdac511>:0) CommNet.CommNetVessel.UpdateComm () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.CommNetVessel.OnNetworkPreUpdate () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.CommNode.NetworkPreUpdate () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.Network.Net4[_Net,_Data,_Link,_Path].PreUpdateNodes () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.Network.Net`4[_Net,_Data,_Link,_Path].Rebuild () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.CommNetwork.Rebuild () (at <2afc64dea36946459d4707808bdac511>:0) CommNet.CommNetNetwork.Update () (at <2afc64dea36946459d4707808bdac511>:0) UnityEngine.DebugLogHandler:LogException(Exception, Object) ModuleManager.UnityLogHandle.InterceptLogHandler:LogException(Exception, Object) UnityEngine.Debug:CallOverridenDebugHandler(Exception, Object)

The post linked below details a similar issue, but doesn't give a solution to the problem.

Can anyone help me fix the problem?
