MD5 Checksum on Guest Additions

[Mikey7117]

I am running a Windows XP Pro SP3(release candidate) and a solaris 10 as a guest OS on VB 1.5.4. I am trying to install the guest additions and quickly get a terminal screen and then it closes. After very close examination, it appears to be complaining about a MD5 checksum mismatch when running VBoxLinuxAddtions.run Any help would be appreciated. I am new to VB and Solaris. -Mikey
