Problem 1) is now fixed in the lasted build (6th May 2007)
Problem 2) without lookin at your data not sure what this referes to It could be scheduled items that have been added to the Account and are not due. When you are in the Account Transaction screen look at the number of uncleared items.
Problem 3) You have not actually installed the new version, just repaired the previous version of the windows installer file. You need to remove the file (Control Panel -> add remove files). No problem with registry, data files do not get removed on uninstall. Corrupted data file is stopping the application from working. You cannot move data files from one pc to another need to run the system transfer function, can cause data corruption.
I have added sufficient information if somone is looking at the forums. Have continued discussion off-line.
