Nsdl E-Governance Infrastructure — E-pan

I applied for my pan card online throught nsdl online server a few days ago and within minutes of applying and paying the amount for e-pan card i got my acknowledgement number. (Since it is not possible go to my home and get the hard copy during this time). When i tried to check my progress through the nsdl server is was saying no record found. I was about to complain about it but the next day my e-pan arrived at my email. But whenever i try to use it at any online service like kotak 811 or even try to link it to my addhar (Which it is already linked because i used my addhar to provide the information while applying) it says invalid pan number. Please help. It is not possible to go to a nearby rbi office and get this sorted out.
