ERROR: “The operation has timed out” or “The underlying connection was closed: An unexpected error occurred on a receive”

Symptom:
Able to load the physical chemistry text book but while reading the book you get  12-20 pop up messages stating either “The operation has timed out” or “The underlying connection was closed: An unexpected error occurred on a receive”. After each of the two messages come up numerous times, the program shuts off and you have to go back and restart the textbook.
Cause:
This is a .NET error as described in this knowledge base article from Microsoft.
Solutions:
a) Download and install all the latest updates for your Windows  OS from
b) Make sure your internet connection is reliable. If you are using a wireless connection, it may be dropped by your router intermittently. A better router may fix the issue. Alternatively you can also try connecting the laptop/computer directly to the router via an ethernet cable.
To ensure that we can investigate the issue  to see if we can do anything else on the software side we have logged bug #122.

Thermodynamics module
Chapters 1 to 6 of Physical Chemistry - Laidler, Meiser, Sanctuary


Includes multimedia that opens on relevant pages and allows the student to visualize many of the concepts by varying parameters and plotting different graphs. Things students often have difficulty with, such as isothermal, isobaric, isochoric and adiabatic process, are clearly visualized.

Physical Chemistry textbook
by Laidler, Meiser, Sanctuary


This popular Physical Chemistry text book is now available in electronic format. We have preserved much of the material of the former hard copy editions, making changes to improve understanding of the concepts in addition to including some of the recent discoveries in physical chemistry. Many chapters have new sections and the coverage of several chapters has been greatly expanded.
