I have reached the limit of my authorizations for ADE.

I had severe problems with my computer and had to re-install windows a lot of times in the last 19 days.

Every time I thought the problems were solved I installed ADE, but after a few days Windows crashes again.
Now I brought my computer to a computershop and they looked it over.

But when I installed ADE3.0 and tried to authorize my computer the message appeared that I reached the limit for authorization on this pc.

But how can I read my ebooks when I buy these?

Can Adobe reset anything, so I can Authorize my computer again?

Please help me.
