Try Xiologix (www.xiologix.com) - I had XPa with expired SA and buying the upgrade to XPe was by far and away the cheapest route back to active SA.
Disclaimer - I used to work for them. :)
Does anybody know of any resellers that might have xpa to xpe upgrade licenses or additional xpa connection licenses? Originally I was looking for a 50 fr3 connection pack but they're all gone it appears. Any help would be appreciated.
