Issues with synchronizing SpiraTeam and Jira using Desktop DataSync

I am using Spira Desktop DataSync to synchronize the SpiraTeam server with Jira. When I start synchronization on the desktop application, it shows that it finds the plug in but then gives me this error:

"

The description for Event ID 0 from source DesktopDataSync cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

Could not load file or assembly 'JiraDataSync' or one of its dependencies. The system cannot find the file specified.
   at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks)

the message resource is present but the message is not found in the string/message table

What could be the problem?
