X1 becomes unresposive a few mins after starting

Ever since I purchased the X1 Search Client with Premium Support, it becomes unresponsive after a few minutes of starting.
Thereafter, it will not start again till I do a Windows restart, and then it becomes unresponsive again.

The Windows error details are appended below.

Would appreciate any information to resolve this problem.

Thanks,
Anil Pande
