In post #7 from your other thread, CatByte asked you to update to the latest version of Java. Check both computers to see if they're using the same version.
Post #13 asks you to increase the security level for Internet Explorer. Where it says In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and (" Initialize and Script ActiveX controls not marked as safe") to "Disable"
, change it to "Prompt". If this doesn't fix the problem, set it back to "Disable".
Apart from that, I can't see anything else in CatByte's instructions that could cause your current problem.
