Upgrading Problems

Im New to the Parallels Forums, and i Hope that this Post fits all the rules.

My Problem... Im really depressed about it...

My Dada bought Me My Parallels Desktop For Mac about a year Ago in London.
Ive been so Happy With it ever since Today...
Today i Went on My Parallels Desktop for mac and Checked if there was an Update, It said that it was, so i installed it.

I was dumb enough to uninstall my older version of Parallels Desktop For mac, and used the v 3.0 expecting it would just work as Causal.

Suddenly it said some error problems, and said that i had to active the thing and reinstall etc. I was so confused that i Reinstalled the newer Version too.

Anyway expecting everything to be fine i installed the Parallels Desktop for Mac that i recieved on my CD Disk. And then i Suddenly Get This Message: http://img339.imageshack.us/img339/7974/picture1pf1.png , Nothing to Install!

So what i Did was install the new Version from Parallels site, and now im Stuck with a Trial Version.

Please Help me with this Problem, I would be gald if anyone could poit out where i could regian the older version of Parallel so my Bought Activation key would work.

Thanks you once again, Dan

 

To fix the problem just use an Uninstaller from the build 4128 (http://download.parallels.com/v3/en/GA/Parallels Desktop 4128 Mac en.dmg) to uninstall Parallels Desktop 3.0, then download and install build 3188.
If you have UK Parallels Desktop version - you can either install it from your CD and run Check for Updates or if you also have 3.0 upgrade key - just install build 4128 again, it should accept your UK key from the previous version and the 3.0 upgrade key.
