Userdefined Ribbon - Blank VBA message box

[Romanoff2011]

I have a problem with a userdefined Ribbon on open the excel file loading data into it with VBA.

Suddenly, during loading data into the worksheet i get a error message.

=> The message box that appears has no words, number or any other information on it. It is a totally blank VBA message box with the 'vbCritical' icon on it (red circle with the white X in it) with 'OK' and 'Help' buttons.

I click on the 'OK' button and the loading continues, everything is loading correct.
[ I load the data from a big txt-file (372MB).]

What it makes me thinking, if the txt-file is much smaller no error message appears.
If i use the 'old'-excel templae without the ribbon, i do not get this error message.

I just found a note in a tm1-forum:
"I have seen cases where the Excel 2007 ribbon is "demolished" when running a (basic) Excel VBA macro."

How can this issue be solved ?
How can this error message be avoided?

Thanks for any comments!

Issue solved.

In Excel2007:
The feature getVisible="GetVisible" and getEnabled="GetEnabled" is not working properly, delete everything of it in XML and VBA.
Also, delete the ******="Ribbon******" in the customUI.XML

Test in Excel2010:
No issue, no problems, there, it seems to work more stable.
