Hello, I am running Windows XP through Parallels 7. Long story short, I need to replace a .dll file related to Access2010 in order to correct a "[Microsoft][ODBC Microsoft Access Driver]Datetime field overflow (null)" error. Basically, this involves replacing the ODBCJT32.DLL file in the system folder with an older version. I've done this a number of times in previous versions of Parallels because every time Windows goes through an update it updates this files, which I then have to replace. However, since upgrading to Parallels 7, I cannot seem to get the fix to take. I've booted in safe mode via the menu and replaced the file, but when I reboot the file has reverted to the previous version. I have not had any success getting Windows to boot in safe mode using F8. I am growing increasingly frustrated with what should have a relatively easy problem to fix. Please help! Thanks!
