Thanks for the post and question. If you could please reply back with the exact error message you are getting when the test fails.
Also, does the test fail every time you run it after the first test run? If the test fails every time after the first test run, please let us know along with posting the exact error.
If the test passes and fails at times, then it might be a timing issue. Please try adding a Delay Step or increasing the step's WaitOnElementsTimeout property in the Visual Studio Properties Window.
But from what I understand of the error you posted, it maybe that the recorded link is not the same on test playback since it maybe generated with a different query string.
If so, please try changing the Find Param for the link to a partial find. You can do this using the 'Contains' property for the link address, remove any query string that is recorded, and use as much of the Url that will be constant for the link for all test runs.
Changing the Find Param explained in the 'Changing how an Element is found' topic in the Quick Start Guide
