There is a problem with the sheet in the Thinnmann Excel Training Log on the sheet tabbed as "TRAINING PLANS".
When you attempt to update it to 2010, this sheet does not update.
It can be manually fixed right now by copy and pasting from an older version of the file before it became interactive.
If you would like me to fix it for you, send me your copy via email and I will take care of it.
In the meantime, I will work on a fix and post it when it becomes available.
