problems with transferred SW license

I have transferred my license from my desktop to my laptop.
I activated the license on my laptop (activation succeeded)
Everytime I want to start SW, it ask again to activate the license.
Then I activatie again the license and every time SW stops to work.
I use SW2008 SP4, with Vista 32 bit.
I have already reinstalled SW2008 and tried with SP0 but theproblem keeps the same.
3 weeks ago I transferred also my license without problems.
Anyone any suggestions for a solution?
