What's This Help not working for one entry in each header file

Question

I have a large RoboHelp project that I have imported into Version 8 from a previous version. Prior to the import into Version 8, all of the What's This Help in the project was working perfectly; now, post-import, I have a problem.
Firstly, some background information.
My project contains a large number of individual header (.H) files, one for each dialog within the software. These header files, which have been generated and provided by our developers, contain one entry for each field on the dialog to which the header file relates. The header files are all contained within a \HTML Topics\Fields\ folder (going from the root of my Help project).
Each header file has a corresponding text (.TXT) file. These text files contain entries that correspond to the entries in the relevant header file. The text files are also contained within the \HTML Topics\Fields\ folder.
Below is an example of the contents of a header file:
#define IDH_HIERARCHY_APPEARANCE_HIEARCHY_LIST          16811
#define IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE         16812    
#define IDH_HIERARCHY_APPEARANCE_REMOVE_APPEARANCE      16813
Below is the contents of the corresponding text file:
.topic IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE
Click this button to add a new row of hierarchical appearance settings to the grid.
.topic IDH_HIERARCHY_APPEARANCE_HIEARCHY_LIST
Use this grid to define hierarchy appearance settings. Each row in the grid represents a level of the hierarchy. For example, the appearance settings you define for the first row apply to the top level of hierarchy, the settings you define for the second row apply to the second level, and so on.
.topic IDH_HIERARCHY_APPEARANCE_REMOVE_APPEARANCE
Click this button to delete the selected row of hierarchical appearance settings from the grid.
The What's This Help that was part of the original project still works perfectly. However, after upgrading the project to RoboHelp Version 8, I have had to update the project to reflect changes to the software. As part of this work, I have imported some new header files and updated some existing ones - and edited the corresponding text files accordingly.
The What's This Help that is covered by the header files that I have imported since the upgrade to RoboHelp Version 8 does not work correctly; in each case, the What's This Help does not work for whichever field appears at the top of the appropriate text file. The position of the entry in the corresponding header file does not make a difference.
If I manually edit a text file to move a different entry to the top then recompile the Help project, the What's This Help does not work for the field that now appears at the top of the text file - and the What's This Help for the field that used to appear at the top of the text file now works.
I've tried everything I can think of to fix this, but nothing has worked. It seems as if there is a problem in the way RoboHelp is compiling the header and text files.
If I use Microsoft HTML Help Workshop to decompile the CHM file, then view the contents of the resulting, decompiled text files, the affected files appear as follows:
.topic IDH_HIERARCHY_APPEARANCE_ADD_APPEARANCE
Click this button to add a new row of hierarchical appearance settings to the grid.
.topic 16811
Use this grid to define hierarchy appearance settings. Each row in the grid represents a level of the hierarchy. For example, the appearance settings you define for the first row apply to the top level of hierarchy, the settings you define for the second row apply
to the second level, and so on.
.topic 16813
Click this button to delete the selected row of hierarchical appearance settings from the grid.
Note how the entry at the top - which relates to the What's This Help that doesn't work - appears differently to the other entries which do work. The name of the ID appears after ".topic" rather than the appropriate ID number.
Any help that anyone can provide me with would be very much appreciated.
Thank you,
Mark

Its working now. We just kept trying to reinstall the tools and restarting indesign. On the 4th time the buttons started working. I can't explain why it finally worked, just that it is working now.
