Spark causing another application to fail

Have a transportation mapping application that, after Spark install, works for a little while (10, 15 minutes), then starts throwing error messages like:

Assert(nCol >= 0 && nCol < m_pRowset->GetColumns().GetSize()) Failed. Cls: AssertException, Thrown at C:\B4_470\Trapeze\Core1\Include\TCF_Rowset.h(1215)

then,

Error in communications with the server. Check your settings and try again later.

Uninstalling Spark will make the problem go away. The spark log show the following error that occurs around the same time as the other app crashing…

Any help is greatly appreciated - I’‘ve been up against a lot of resistance replacing OPN with Wildfire and Spark, and this isn’'t helping my cause. Thanks again!
