Does 4.000 uninstall other MTU programmes?

[Garry A. Leslie]

Hey Admin,
I bought 4.000 and downloaded it 16th March.
I had put all my MTU programmes on a new laptop (with your permission)
Now on going into the other programmes I get the "serial number doesn't match", error.
Microstudio was the last one I installed, has this also got a problem like 2.613 where it uninstalled the other programmes?
Although I only installed it on the above date the link expired on 26th March, just 10 days after the download, my Hoster 3.316 has also expired, haven't checked my account for the others.
How can I get them back?
Also is there an update to 4.001?, doesn't say anything in your sales pitch.
Regards from across the pond.
