Hi all
I am about to migrate my BIAB to a windows 7 PC
As I have have been a regular MegaPAK upgrader since (at least) BIAB 10 untill BIAB 2010, I expect to install from every CD/DVD on top of each other in order to keep all the "extras" that I stil want to use. (E.g on the oldest BIAB MegaPAK CD's the product 'Master Jazz Guitar Solos' were delivered)

My problem, however, is that when I insert the BIAB 10 CD in the win 7 machine, it is not readable.
Next problem is that when I insert the CD in the very same XP machine that I installed on 4 years ago, it is not readable on that either. In fact it stalled the disc drive so I had to force it opened.

Now to the questions:
Have any of you experienced that the old CD's wear out/get unusable over time? (They have not been exposed to any extreme climatic environments since last install).
Do you have any alternative strategy for migrating years of compiled BIAB stuff to another computer?
