Iota wallet shows "No connection"

[andigesi]

Hello,

first of all ? sorry if this is an odd topic for this forum.
But I also posted it in the Iota forum and no-one seems to be there.

I was using Iota Light Wallet 2.4.0 on my old Macintosh Laptop (OS 10.12.6).
In the meantime I switched to a new laptop and did not check my account for a while.
Now it turns out, the software on my old laptop only shows "no connection" when I open it.

I read in a forum that I should download Trinity, which I did (to my new laptop).

The problem is ? the seed that I needed for Iota Light Wallet was 60 characters long.
Trinity is asking for a 81 characters seed (which I havenot got).

What can I do to get access to my Iota currency somehow?

Thank you and best wishes,
Andi
